| 摘 要： | 研究了复合材料整体加筋板在轴压作用下的后屈曲传载机制: 采用商业有限元软件ABAQUS建立加筋板有限元模型, 对其轴压后屈曲过程进行了模拟; 并对局部屈曲和总体屈曲阶段的内力情况以及传载特性进行了细致的分析, 获得了节点线与反节点线的合力和力矩的分布规律。计算结果与试验数据吻合良好。最后指出了节点线与反节点线是后屈曲阶段缘条/蒙皮界面最先可能失效的位置, 并指出了诱发失效的主要原因分别为合力矩Mxy和My。

| Abstract: | The load transfer mechanisms at the post-buckling stage were studied for an integrated stiffened composite panel subjected to uniaxial compression.An FEM model was created for the panel by using the commercial software ABAQUS.The post-buckling process of the panel was simulated under uniaxial compression.The internal resultant forces and the load transfer mechanisms were discussed in detail at different stages(i.e.,the local and global post-buckling).The distributions for resultant forces and moments at nod... |
