Experimental Investigation of Nonelastic Deformation Emphasizing Transient Phenomena by Using a State Variable Approach

Source

This paper reviews the development of a deformation model based on a state variable approach for nonelastic deformation. The material parameters required can be determined by a combination of load relaxation and constant displacement rate tests. The experimental procedures, methods of data analysis, and the physical significance of the material parameters are discussed. The deformation model has been used to simulate a variety of deformation phenomena and has been compared with experimental data.
