Endochronic viscoplasticity model
The endochronic viscoplasticity model is presented, and the criteria for general problem analyses are discussed. Two approaches are then developed for inclusion of this model in nonlinear finite element codes. One approach includes reformulating the stiffness matrix for solution by iteration, and the other approach does not. Also, the uniaxial tension problem is studied, and the problems encountered with the use of this model are stated. Finally, recommendations are presented to check the basic postulates used to develop this model.
