本文借助于摄动法用分段线性加载面讨论了弹塑性结构在准静态载荷下的安定问题,给出了一个普遍适用的不等式,由此导出了广义的米兰(Melan,1938)安定准则以及位移与塑性变形的界,并举例进行了说明。
In this paper, we discuss the stability of elasto-plastic structures under quasi-static loading by using perturbation method with piecewise linear loading surface. A general applicable inequality is given. The generalized Milan (Melan 1938) stability criterion and Displacement and plastic deformation of the community, and an example was described.
