用三维实体单元分析薄壁箱型结构应注意的问题

Issues in thin-wall box structure analysis using 3D solid elements

从四边固定正方形板受均布载荷的经典问题入手,结合不同类型单元的特点,探讨应用三维实体单元分析薄壁箱型结构时应注意的几个问题,纠正三维实体单元分析和应用的误区,为提高结构分析计算结果精度提供参考.

Starting from the classic issue of the effect of uniform load on square plate with four fixed sides, several issues that should be paid attention to during the thin-wall box structure analysis using 3D solid elements are discussed combining with the characteristics of different types of elements, and the misunderstanding of the solid element analysis and application is rectified. The results can provide reference for the accuracy of structure analysis and calculation.
