Item type:Publication, Access status: without files , Development of a new proof of plate capacity under combined in-plane loadsIn this paper, the development of a new proof of plate capacity under combined in-plane loads for ship design and classification is described. The new proof is based on an improved understanding of plating collapse obtained from an extensive series of non-linear buckling analyses using the finite element method and covering the full range of structural configurations and load combinations relevant for the shipbuilding industry. Compared to existing proofs, the new proof incorporates a more physically based approach towards tensile stress effects on plate capacity and better captures the influences of both plate slenderness and aspect ratio under compressive biaxial loads. Moreover, the new proof can be solved without the need for iterations and may be used directly with stresses obtained from finite element analyses, thereby eliminating the need for a correction of stresses due to Poisson effects.Publicationtype: Journal Article130 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Ultimate strength of ship plating - A proof of capacity under combined in-plane loads(2016-11); The need for a proof of plate capacity under combined in-plane loads is addressed. An extensive series of numerical studies based on the finite element method is performed covering all load combinations and plating configurations relevant for the shipbuilding industry. These studies are used to investigate the mechanics of plating collapse and to evaluate existing proofs of plate capacity. In order to satisfy both qualitative and quantitative acceptance criteria, a new proof of plate capacity under combined in-plane loads is developed. Practical application of the proof in design is presented.Publicationtype: Doctoral Thesis510 1562 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Application of a new proof of plate capacity under combined in-plane loads(2016); A new proof of plate capacity under combined in-plane loads has been developed based on an improved understanding of collapse gleaned from an extensive series of non-linear buckling analyses using the finite element method and covering the full range of plating configurations and load combinations relevant for the shipbuilding industry. Compared to existing proofs, the new proof incorporates a more physically-based approach towards tensile stress effects on plate capacity and better captures the influences of both plate slenderness and aspect ratio under compressive biaxial stresses. Moreover, the new proof can be solved without the need for iterations and may be used directly with stresses obtained from finite element analyses, thereby eliminating the need for a correction of stresses due to Poisson effects. However, this new proof is based on a number of simplifications pertaining to boundary conditions, applied loads and initial imperfections. Because any or all of these assumptions may be violated in practice, the purpose of this paper is to demonstrate that the new proof remains valid in case of other boundary conditions, additional load components and initial imperfections which are more realistic.Publicationtype: Conference Paper48
