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 Article28 24 - 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. Despite their mechanical advantages, composite structures remain vulnerable to buckling, necessitating the use of accurate computational modeling to ensure reliability. A total of 1855 Scopus-indexed publications were analyzed using Bibliometrix and VOSviewer. 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 Article28 10 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , A review of composite materials for marine purposes: Historical perspective and current state(Elsevier, 2025); ; ; This study offers a concise review of the application of composite materials in marine environments, encompassing both historical perspectives and current conditions. Composite materials, which are both lightweight and robust, have been widely used in maritime structures, such as ships and offshore platforms, to enhance resistance to structural failure. The main focus of this study encompasses three aspects: the historical development of composites, failure theories of composite materials with an emphasis on damage caused by external loads, and recent advances in failure criteria for durability optimization. In this study, several failure theories, including the maximum stress-strain, Hashin, Tsai-Hill, Tsai-Wu, and Puck theories, are presented and reviewed, along with recent research results presented in tabular form. The expected results of this study can provide essential guidance for future research directions aimed at enhancing the reliability of composite materials in the maritime sector.Publicationtype: Conference Paper14 13 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Analysis of the ballistic impact on sandwich panel : influence of attack angle and target location in structure–bullet interaction(Springer, 2024-09-09); ; ; ; This study presents a numerical investigation of bullet impact on sandwich panel structures. This research aims to demonstrate the ideal performance of sandwich panel structures in resisting ballistic loads based on the type of core geometry and materials used. Numerical simulations were conducted using the Johnson–Cook material model and applied in ABAQUS/Explicit software. Parameters such as shot target location and bullet angle of attack were considered in this study to review the structure’s resistance to ballistic loads. The results showed that the sandwich panel structure with decagon core geometry and Armox 500 T material was optimal in resisting the impact of blunt bullets at 500–700 m/s. The contribution of this research is to provide understanding in the field of ballistics by showing the interaction between the sandwich structure and the bullet through the velocity drop that occurs on the bullet and the energy the structure can absorb. Overall, this research provides insight into improving the design and performance of protective structures.Publicationtype: Journal Article40 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Environmental impacts caused by fire and explosion accidents in maritime activities: a review(EDP Sciences, 2024-08); ; ; Over the past few years, marine transportation accidents have decreased significantly. Marine transportation accidents are complex events often caused by multiple factors through the interaction of multiple parties. These accidents can cause loss of human life and property and ecological and environmental damage. They could disrupt the balance of the industrial and economic situation. This paper comprehensively reviews Fire and Explosion (F.E.) accidents in maritime activities. The subject is narrated through a brief history and the resulting impact on the surrounding marine ecosystem. Then, the study summarizes the policies and regulations derived from international maritime agencies that have governed prevention and countermeasures. Therefore, preliminary research on enhancing the safety and security of composite-based structures is summarized in this review to highlight protection and prevention programs in the maritime scope. Overall, this study covers the current state of the global maritime industry and the policies and regulations for protection from fire and explosion accidents.Publicationtype: Conference Paper11 40 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Assessment of ship collision risk based on the recorded accident cases: Structural damage and environmental recovery(EDP Sciences, 2024-08); ; Transportation is vital due to its capability to transport cargo and people massively. However, if maritime accidents take place, they may cause a significant impact not only on the economy and lives lost but also on the environment. This review paper provides a summary of research and reports on marine accidents, including the inclusion of ship type effects, types of accident events, and the accident consequences, especially to the marine environment. The paper covers global accident data, accident reports from various global accident investigation authorities, and the investigation results. Overall, this study aims to highlight the global tendency of marine accidents and how the accident affects the surrounding site's environmental condition. Additionally, the regulations and activities for environmental recovery are elaborated to tackle the damage caused by the ship accident. The contribution of this review is expected to provide a broader view of the maritime casualties and the effects on the marine environment and the regulations to overcome the damaged ecosystem.Publicationtype: Conference Paper13 29
