摘要: 对结构优化中常用的二维连续体单元进行讨论,论证了取诸节点处Mises应力最大值作为应力约束的合理性.

关键词: Mises应力最大值, 应力约束

Abstract: Common elements for the optimization of plane continuum structures are discussed. It is verified that adopting the maximum of Mises stress on all of the nodes of the element as the stress constraint is reasonable.

Key words: the maximum of Mises stress, stress constraint
