| 摘 要： | 分别用ANSYS软件的实体单元solid-46.基于一阶理论的壳单元shell-99和基于整体-局部高阶理论有限元计算了复合材料层合/夹层板结构,包括层合板孔边应力集中和层合板热响应的算例,比较了各算法的精度.计算结果表明:ANSYS软件不能准确计算层合板/夹层板的层间应力,对孔边应力和热响应问题精度较低,整体-局部高阶理论有限元对于上述问题的计算具有较高精度.

| Abstract: | By analyzing several numerical examples,the solid and the shell elements of ANSYS as well as finite element based on the global-local higher-order theory are estimated in this paper.Numerical results show that ANSYS is unable to calculate accurately interlaminar stresses around the curved free edges and thermal stresses of laminated composite plates.However,the finite element based on the global-local higher-order theory can predict satisfying results for these problems. |
