摘要
从变分不等式出发，结合有限元，建立了按增量求解薄板弹塑性弯曲问题的线性互补方程。从而既无须迭代又避免了有效内力的漂移。
Finite Elemnent-Linear Complementary Equation is established for analysis of elasto-plastic thin plate-bending problems based on variational inequality principle.In this method,iteration procedure is disregarded,and the drifting of yield function from yield surface is controlled.
