摘要
本文提出了多晶金属屈服的非线性不可逆增殖模型，导出屈服动力学方程及屈服应力表达式，对有关用屈服现象和实验结果给出了较合理的解释．
Abstract In This paper a yield model of polycrystalline metals, based on the nonlinear irreversible multiplication of deformed grains, is proposed,from which the kinetic yield equations and yield stress formulas are deduced. Some yield phenomena and experimental results can reasonably be explained.Keywoads:yield;dislocation; multiplication
