en سازه کشتی Ship Structure مقاله پژوهشي Research Paper <div style="text-align: justify;">This paper presents the collapse behaviour of a composite ship hull girder under vertical bending. Finite element method is used to provide valuable information regarding moment-curvature relationships and progressive failure characteristics of the composite ship hull girder. The analysis is carried out using ANSYS 12.0 finite element software. The response of the structure to the incrementally-increased sagging and hogging bending moments has been implemented and studied.&nbsp;</div> Composite ship hull girder, Vertical bending, Progressive failure, Ultimate strength, Finite Element Method (FEM)‎. 21 32 http://ijmt.ir/browse.php?a_code=A-10-7-3&slc_lang=en&sid=1 Sepideh Jafarzadeh sepideh.jafarzadeh@ntnu.no 10031947532846003572 10031947532846003572 No Department of Maritime Engineering, Amirkabir University of Technology Mohammad Reza Khedmati khedmati@aut.ac.ir 10031947532846003573 10031947532846003573 Yes Department of Maritime Engineering, Amirkabir University of Technology
