Abstract

Abstract

Usually, in tha study of elasto-plasticity, the assoiated plasticity,i.e the plastic potential surface coincides with yield surface,is often used.However in practical problems, there are many materials which do not obey the associated plastic flow rule, For instance, the mechanical behavior of rock, concrete,etc.must be described by the. nonassociated flew rule when deformation occur, In This paper,by means of the nonsymmetric Laz-Milgram lemma, we shall discuss a series of important questions of the nonassociated plasticity in detail.
- nonsymmetry,
- nonassociated plasticity,
- existence,
- uniqueness
