Abstract
Based on relationship between elastic and plastic strain, a new basic equation system of plasticity mechanics was established. In this paper, modification is made to the new basic equation system, and another form of basic equation system is presented based on stress strain constitutive relation, which also makes it possible to apply the results from elasticity mechanics directly to plasticity mechanics and decreases the solving difficulty of plastic problem. Finally, a simple application example is given, which shows that the new form of basic equation system is correct and practicable.
