| 摘 要： | 基于更新拉格朗日格式,应用非线性层合三维退化壳元,结合有效的复合材料失效准则、刚度退化模型以及文中提出的刚度矩阵奇异判断准则,对复合材料层合板在轴向载荷作用下的轴向压缩极限强度问题进行深入研究.讨论了铺层方式、板厚等对极限强度的影响.通过与试验结果进行比较,表明基于文中提出的刚度矩阵奇异判断准则,结合增量更新拉格朗日格式下非线性层合三维退化有限元的计算方法能有效计算复合材料层合板的轴向压缩极限强度,并具有很高的精度.

| Abstract: | Based on effective composite material failure criteria, property limited degradation model, axial compressive ultimate strength of composite laminated panels were analyzed deeply by nonlinear laminated degenerated 3D finite element analysis, which based on incremental continuum-based updated Lagrangian formulation.In order to get the ultimate strength point of structure accurately, the criteria for judgment of singularity of matrix, was presented.The effects of stacking sequences and thickness of lamina on ... |
