Abstract: Tang's model was simplified and extended to three dimensional space based on the assumption in plasticity theory. A user defined material subroutine (UMAT) is developed for ABAQUS application. Simulations for quasi-static tensile experiments with the pseudoelastic TiNi alloy specimen are conducted and the results agree well with the experimental data.
