Paper Abstract

An analytical model of the pseudoelasticity of shape memory alloys (SMA) has been developed and validated using tensile test results performed with various kinds of shape memory alloy samples. However, the analytical approach is limited to conventional samples submitted to an uniaxial stress state. Therefore, a numerical model has been developed, which is more suitable for the adaptive structure modeling. To this end, the SMA behavior laws have been implemented in the finite element code ATILA. The validation of the numerical model has been achieved by comparing the finite element results with the experimental ones.
