A state variable approach was developed based on experimental results to describe a variety of nonelastic deformation phenomena including anelasticity, microplasticity, macroplasticity, grain boundary anelasticity and sliding, and the Bauschinger effect. The experimental results were obtained mainly from the load relaxation and the constant displacement rate deformation test. The state variable constitutive equations were used successfully in stress analysis and in problems of current technological interest. The research was extended to develop microstructural based theories and to investigate deformation related phenomena such as grain boundary cavitation.
