| Abstract: | The plastic strain rate is a key factor that represents the dynamical charateristic of ma- terials under plastic state.The plastic strain rate must be considered in the plastic dynamics. Based on the constitutive realtion of elastic viscoplasticity,the incremental functional is de- rived by means of non-linear functional analysis theory in this paper. |
