本文推导了应用于直接法解薄板弹塑性问题的边界积分方程,并着重推导了内点广义应变率的计算公式,为薄板弹塑性分析的初始应力及初始应变法提供了基础。
In this paper, the boundary integral equations for the elasto-plastic problems of thin plates are deduced by direct method, and the formulas for the generalized strain rate at the inner points are deduced, which provide the basis for the initial stress and initial strain method of elastic elastoplastic analysis of thin plates.
