| 摘 要： | 基于大型有限元著名软件ABAQUS,对复合材料梁有限元分析进行了研究.以承受均布荷载的悬臂梁作为实例进行分析,根据Lekhniskii的各向异性弹性理论应力解答,推导得出梁弯曲轴线的方程,然后把有限元数值计算结果与各向异性弹性理论解答对比分析,验证ABAQUS对复合材料梁建模分析的正确性,并讨论材料各向异性、材料弹性主轴方向以及高跨比对结果的影响.

| Abstract: | Based on ABAQUS,the finite element method analysis for the anisotropic beam is conducted.As an example,a cantilever beam under a uniformly distributed load is considered.Based on Lekhniskii's anisotropic elasticity solutions of stresses,the equation of the bent axis is derived and then assessments are made for finite element method solutions by comparing with anisotropic elasticity solutions.The justification of the finite element method analysis is illustrated by the example.Several sets of numerical results are presented to show the effects of anisotropy ratios,the principal directions of elasticity and the thickness-to-span ratios. |
