TiNi alloy shape memory alloy material test system elastoplastic constitutive relation three dimension ABAQUS numerical simulation
For the particular phenomenon in the quasi-static stretching of TiNi alloy,a one-dimensional constitutive relation of shape memory alloy(SMA) is extended to three dimension based on experiments and elastoplastic theory.Quasi-static experiments are conducted on a hydraulically driven load frame(Material test system,MTS).A user defined material subroutine(UMAT) is developed for ABAQUS application.Simulations for the abnormal fracture behavior of TiNi alloy are conducted and the results show a good accordance with the experimental results.All that can afford a certain reference for the experimental design of SMA.
