Extended thermomechanical model for NiTi-based shape memory alloys with plasticity
Original language description
This work presents a thermodynamically formulated model of shape memory alloys (SMAs) extended by the element of plasticity. The model is designed to simulate the response of polycrystalline NiTi-based SMA materials. Its features include a description ofthe transformation between austenite, R-phase, martensite and its reorientation. This model has been improved with von Mises plasticity with linear hardening in martensite, the additional dissipativeprocess. The model together with the extension is created within the framework of continuum thermodynamics of irreversible processes. The model was implemented into the finite element software Abaqus via UMAT subroutine. Several simulations were carried out for a description of its behavior under loading and the response of the model was compared with experimental results.
