Plastic Analysis of Thin Plates with Anisotropic Hardening

摘要: 本文讨论了当薄板受到反复加载时由于存在鲍兴(Bauschinger)效应必须运用各向异性强化模型。文中导出了在线性随动强化时如何用广义力及广义塑性变形来表示薄板的加载条件,并讨论了可推广应用于非线性随动强化及混合强化(Mixed Hardening)情况。最后还以圆板为例进行了数值计算给出了计算结果。

Abstract: In this paper we discuss the adoption of the anisotropic hardening model due to the existence of Bauschinger effect when thin plate is applied by repeated loading, The loading condition of thin plates for linear kine matic hardening has been deduced in terms of generalized forces and generalized plastic deformation, And it can be extended to non-linear results kinematic hardening and mixed hardening, hinally as an example the numerical are obtained for a circular place.
