Finite element simulation of martensitic transition based on thermo-mechanical model
چکیده انگلیسی

Martensitic phase transition and martensite phase have an important effect on the physical and deformation properties of a material. In this paper, martensitic phase transition in elastic materials is modeled by using thermo-mechanical phenomenological theory. Based on the model proposed, stress-induced martensitic transition in Cu–Zn–Al shape memory alloy is studied by using finite element method. Stress–strain responses of Cu–Zn–Al single crystals under different applied stress rate are simulated by thermo-mechanically coupled calculation. Pseudoelastic deformation, hysteresis of transformation and hardening in stress–strain response are predicted in calculation results. Stress–strain curves determined from numerical simulation have a good agreement with those observed in experiments.
