형상기억합금의 개선된 Liang-Brinson 모델

초록

This paper proposes a thermodynamic constitutive model of shape memory alloys, which is based on the Liang-Brinson model. In this model, the rubber-like effect at temperature below is augmented to complement some important features lacking in Liang-Brinson model. By comparing numerical results with the experimental data, the proposed model is shown to better simulate the thermomechanical behavior of SMAs in an extensive temperature range to generate more accurate prediction.
