摘要

从Masing二倍法构造的Hardin-Drnevich模型的卸荷再加荷滞回曲线出发，以热力学定律为基础，考虑了塑性中心的移动为直线和骨架曲线两种情况下的耗散函数表达形式，应用Ziegler正交条件，通过对耗散函数求一阶偏导，得到耗散应力空间中的屈服函数表达式，并引入耗散应力和真实应力之间的差别项即转移应力，从而得到真实应力空间中的屈服函数。屈服曲线的绘制表明了对于塑性中心的不同转移规律，屈服曲线遵循同样的变化规律：应变在某一范围内，剪切形的屈服曲线是直线形式；当应变超过某一阈值时，剪切形的屈服曲线呈现弯曲。此外，还给出了应变的阈值。

Abstract

Starting from the unloading and reloading hysteretic curves of the Hardin-Drnevich model

different expressions of dissipation function are formulated in order to reconsider the energy dissipation mechanism of H-D model based on the thermodynamics principle. Two kinds of different translation rules of the back stress are assumed: one is the straight line; the other is the skeleton curve; and then the yield function expressions in the dissipative stress space are obtained by using of Ziegler’s orthogonality condition. Moreover

adding the shift stresses to the dissipative stresses

the form of the yield condition in the true stress space is deduced. The plotting of yield curve in true stress space indicates that the form of the shear yield curve is straight line for the two different shift rules when the shear strain is below the threshold value. However

when the shear strain is above the threshold value

the shear yield curves appear bending.
