2119 軸圧縮荷重を受けるFRP管の破壊実験と解析(G01-2 計算力学(2),G01 計算力学)

抄録

In this study an axial compression test for a square FRP tube was conducted to observe the failure mode and a finite element analysis using LS-DYNA was also done to simulate it. To express the splay failure mode, the surface tiebreak method, where the layered shell elements are separated with a certain failure criterion, was employed as well as the constitutive equations based on the progressive damage model. The calculated deformation procedure is similar to the observed splay mode and the obtained load displacement curve was in good agreement with the experimental one.
