Item type:Publication, Access status: with files , Ultimate bending capacity of wind turbine tower structures: a new empirical formulation based on the geometric and material factors(Cerebration Science Publishing, 2026-03-16); ; ; ; Wind energy is emerging as the most promising sustainable energy source due to its abundant resources and environmental benefits. One of the most essential parts of a wind turbine system is the tower, as it is responsible for supporting the weight of the tower top and the loads given by its environment. The preliminary design of the tower section of the wind turbine system is crucial to ensure the system's safety, and a simplified formula is needed to make it more practical. A comprehensive series of ultimate strength analyses on tapered pipes was performed to optimize the tower design, involving the variation and cross-combination of numerous geometric and material parameters. A total of 900 tapered pipe configurations were assessed using finite element method (FEM) analysis via the ABAQUS/CAE program. In the case of tapered cylindrical shells length variations, there was an increase in bending moment from the plastic deformation phase to the critical phase of 29%, 31%, and 39% for pipes measuring 50 m, 30 m, and 10 m, respectively, with the highest ultimate moment of 278.7 kN•m achieved at a pipe length of 50 m. The ultimate bending moment values were then formulated through regression analysis, resulting in a derived formula to predict the ultimate bending capacity of tapered pipes for wind turbine structures. The findings revealed that varying multiple parameters significantly impacted the ultimate strength and critical failure modes of the tapered pipe. The newly developed formula showed good accuracy, providing a reliable tool for design predictions.Publicationtype: Journal Article15 10 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Buckling behavior of thin-walled cylindrical shell structure under axial compression: A study of imperfection parameters with FE approach(Springer, 2026-03); ; Cylindrical shell structures are widely used in engineering applications, particularly in ships and aircraft, due to their high strength-to-weight ratio and efficiency in resisting compressive loads. However, these structures are susceptible to failure through buckling, especially when imperfections such as load eccentricity, thickness variation, and initial geometric deviations are present. This study examines the structural response of thin-walled cylindrical shells subjected to axial compression, taking into account various imperfections. A finite element (FE) approach using ABAQUS software was employed and validated against previous experimental data. A parametric study was conducted using varying load eccentricity, initial geometric imperfections, and longitudinal thickness. The results show that load eccentricity significantly reduces the ultimate load and shifts the location of deformation. Both geometric and thickness imperfections also affect structural strength and the location of buckling. These findings enhance the reliability and safety of cylindrical shell designs in engineering applications.Publicationtype: Journal Article25 23 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Assessment of risk, safety, hazard, and economic challenges of CCS pipeline and wellbore implementation: exploring emerging achievements in 2010–2025(Elsevier, 2026-02-12); ; ; ; Carbon capture and storage (CCS) is widely regarded as a strategic mitigation option for reducing CO₂ emissions from fossil fuel–based industries and the energy sector, in line with global efforts to limit the rise in average temperature to below 1.5 °C. Despite its potential to deliver substantial carbon reductions, CCS deployment remains challenged by a range of technical, economic, and operational risks that must be systematically addressed. These risks arise across nearly all stages of the CCS value chain, including CO₂ capture, transportation, and storage. Over the past decade, research on CCS has expanded rapidly, and several review studies have attempted to map emerging research trends in this field. However, existing reviews have generally concentrated on individual components of CCS technologies, such as carbon capture processes or the safety of geological storage. These studies have not adequately examined the interdependencies across the entire system. In contrast, the present study provides a more comprehensive perspective by assessing the whole CCS chain, thereby offering a systemic understanding of its performance and implementation challenges. The novelty of this work lies in its integrative approach, combining risk and safety analysis, hazard identification, and economic evaluation, with particular emphasis on the transportation and storage stages. In addition, recent advances involving modern technologies aimed at enhancing CCS safety and sustainability are discussed to highlight potential directions for future research.Publicationtype: Review Article21 19 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Composite buckling performances for energy structures and infrastructures: a milestone analysis based on finite element research (2000–2025)(2025-12-17); ; ; This study presents a targeted bibliometric analysis of research on composite buckling in energy infrastructure, focusing on works that utilize the finite element method (FEM) between 2000 and 2025. The increasing demand for renewable energy systems has intensified the use of lightweight composite materials in structural elements such as wind turbine towers, solar supports, and offshore platforms.

The data span 294 journals and over 4200 authors, with China, the United States, and India leading in output. Key publishing platforms include Composite Structures and Thin-Walled Structures. Mapping of keywords, co-authorship, and citation networks indicates that FEM is the dominant analytical tool for assessing buckling behavior, especially in studies involving optimization and failure prediction. This review synthesizes significant developments in the field and reveals the integration of computational mechanics and advanced materials within the energy sector. The results serve as a reference for researchers seeking to enhance the structural resilience of composite-based energy systems.Publicationtype: Journal Article27 10 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Structural integrity of designed sandwich panels under low temperature conditions: blast effect assessment using finite element simulation(Springer, 2025-11-25); ; ; This research employs a detailed finite element analysis to investigate the blast resilience of metallic sandwich panels under various thermal and structural conditions. The investigation considers a range of parameters, including core shapes (tetragonal, hexagonal, and octagonal), core heights (0.021 m, 0.051 m, and 0.081 m), levels of pre-existing damage, and TNT charge masses (0.5 kg, 1.5 kg, and 2.5 kg), all tested under three distinct temperatures: ambient (293 K), sub-zero (193 K), and cryogenic (113 K). Blast loading is simulated using the ConWep method with a consistent stand-off distance of 0.1 m. The findings reveal that panels with octagonal cores significantly outperform other geometries, reducing front-face deflection by up to 46%. Similarly, increasing the core height leads to a more than 60% reduction in back-face deformation. Cryogenic conditions further enhance the structural response, with simulations showing faster kinetic energy decay and a smoother stress distribution across both damaged and intact models. Cryogenic panels absorbed up to 25% more internal energy while maintaining lower overall strain levels, indicating a more efficient mechanism for dissipating blast energy. Overall, the study highlights how geometric configuration, thermal environment, and damage state collectively govern the blast performance of sandwich panels, offering valuable guidance for designing high-performance protective structures in sectors such as aerospace, defense, and cryogenic systems.Publicationtype: Journal Article29 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Mechanical behavior assessment of dynamic ice forces using FE method: Interaction with an idealized offshore structure(Elsevier, 2025-10); ; ; Dynamic interaction between sea ice and offshore structures is a critical factor in design for operations in cold regions. This study investigates ice impact through numerical simulation to provide information relevant to offshore structural design. A finite element model was developed to simulate the collision between an ice sheet and a conical structure, with ice velocity as the primary parameter. The calculations were carried out using an explicit dynamics approach, which enables the simulation of time-varying impact forces. The results indicate that higher ice velocities result in greater stress within the ice sheet, generating larger reaction forces on the structure, with the increase following a nonlinear trend. These findings provide quantitative insight into the magnitude of loads that may be transmitted to offshore structures, underscoring the importance of accounting for dynamic ice forces in structural design.Publicationtype: Conference Paper24 13 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Effect of geometric imperfections on CO₂ transport pipelines under fatigue loading(Elsevier, 2025-10); ; ; ; Ganendra, BenCatastrophic failures of CO₂ transport pipelines can result in severe economic losses and even casualties. During operation, pipelines are subjected to cyclic loading, which may lead to fatigue failure. The presence of geometric imperfections (GI) arising from installation processes introduces uncertainty that can affect the pipe’s strength under these conditions. This study assesses the impact of dent-type GI on the fatigue resistance of CO₂ transport pipelines using a validated finite element method (FEM). Fatigue analysis was conducted using the hot-spot stress approach on the straight tubular pipe with dent-type GI ranging from 0% to 20%. The pipe material is ASTM A36 steel, and the boundary conditions represent an onshore buried pipeline. The results show that the higher the percentage of dent-type GI, the lower the fatigue life due to the stress concentration effect. Further experimental tests and fluid–structure interaction studies are recommended to extend these findings.Publicationtype: Conference Paper47 9 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Grounding damage of stiffened hull panels: a numerical study on orientation effects and seabed-shape-driven energy dissipation(Elsevier, 2025-10); This study integrates experimental and numerical insights from stiffened-plate penetration tests with analytical seabed geometry to interrogate grounding damage. Using a canonical indenter–plate configuration for stiffened panels, hull penetration resistance is assessed against seabed conditions represented by binormal and polynomial rock geometries. Real multibeam bathymetry is interpolated into continuous surfaces and introduced as rigid indenters, enabling direct comparison between simplified plate-level fracture mechanics and complex grounding loads. Finite element analysis (FEA) with ANSYS LS-DYNA examines three orientations: horizontal (lateral seabed intrusion), vertical (local stranding), and 45° (combined penetration/raking). Results show fracture initiation is governed by local stiffener–plate interactions. Damage evolution and absorbed energy depend strongly on seabed roughness and the projected contact area, thereby linking the fidelity of analytical rock models to penetration resistance.Publicationtype: Conference Paper38 13 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Effects of crevice corrosion induced by biofouling on the mechanical response of engineered plate designs as an idealization of naval and marine structures(Elsevier, 2025-08-08); ; ; This study investigates the reduction in the mechanical strength of stainless-steel plates resulting from crevice corrosion induced by biofouling. A hole model based on the geometric characteristics of damage from 6-, 12-, and 36-month immersion data was developed and applied in ABAQUS CAE using the analytical mapped field feature. Finite element method (FEM) simulations were conducted using two types of loading—concentrated and uniform—with 15 random hole configurations each. The results were validated using Kirchhoff-Love plate theory. The results showed that corrosion reduces plate strength, as evidenced by increased deflection, strain, and von Mises stress with immersion duration. Under concentrated loading for 36 months, deflection increased by 10.65 %, strain by 17.22 %, and von Mises stress by 8.87 %. Under uniform loading, the increases were greater: 14.38 %, 43.26 %, and 22.03 %, respectively. A concentrated stress pattern emerged at the center of the plate under concentrated loading and spread diagonally under uniform loading. These findings provide a basis for predicting residual strength and designing biofouling-resistant marine structures.Publicationtype: Journal Article32
