1) back stress
背应力
1.
It has also shown that there are some difficulties on the definition of back stress as the “center” of the yield surface in the Cauchy space.
在推广Ｌｕｃｃｈｅｓｉ和Ｐｏｄｉｏ＿Ｇｕｉｄｕｇｌｉ（１９８８）的带弹性范围物质理论的基础上，表明了背应力作为Ｃａｕｃｈｙ应力空间中屈服面“中心”的定义存在问题·背应力是Ｌａｇｒａｎｇｅ型变量，只能定义在Ｌａｇｒａｎｇｅ型应力空间
2.
Starting from the skeleton curve and hysteresis loop of Hardin-Drnevich model for soils,the dynamic incremental dissipation function is constructed by use of assumption of translation rule of the back stress,in which the shift stress is assumed to be the product by the plastic modulus and the internal variable.
