| 摘 要： | 从非局部连续场论出发，假定形变与局部转动均属微小，当存在体力矩出现非对称应力场时，设对称应力的能量函数和非对称应力的能量函数可以独立计算。基于热力学原理和屈服面的概念，建立了一种新的非对称－非局部弹塑性力学理论。

| Abstract: | By the nonlocal continuum theory,with small strain and small local rotationassumption,we consider the effect of body couple for asymmetric stress field by assumingthat the energy functions of symmetric and the asymmetric part of stress can be formulatedindep endent ly By means of t he principle of thermo dynamics and the concept of yieldsurface,a new t heory for nonfo cal asymmet ric elasto- plasticity is est ablished. |
