Transformation induced plasticity is defined as the plastic flow arising from solid state phase transformation processes involving volume and/or shape changes without overlapping the yield surface. This phenomenon occurs in shape memory alloys (SMAs) having significant influence over their macroscopic thermomechanical behavior. This contribution presents a macroscopic three-dimensional constitutive model to describe the thermomechanical behavior of SMAs including classical and transformation induced plasticity. Comparisons between numerical and experimental results attest the model capability to capture plastic phenomena. Both uniaxial and multiaxial simulations are carried out.
