二维连续体结构优化中常用单元应力约束的有效处理

AN EFFECTIVE APPROACH OF STRESS CONSTRAINT IN COMMON ELEMENTS FOR THE OPTIMIZATION OF PLANE CONTINUUM STRUCTURES

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．

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.
