Cyclic thermomechanical behavior of a polycrystalline pseudoelastic shape memory alloy
In this work, 3D finite element modeling is employed to examine the thermomechanical behavior of a polycrystalline Ni–Ti shape memory alloy in the pseudoelastic regime.

| description | In this work, 3D finite element modeling is employed to examine the thermomechanical behavior of a polycrystalline Ni–Ti shape memory alloy in the pseudoelastic regime. It is shown that the tension-compression asymmetry during uniaxial cyclic loading is due to a preferred orientation of the crystallographic texture. In pure shear loading, the thermomechanical behavior exhibits symmetry in both senses of shear, due to the fiber texture of the specimen bar stock. It is also shown that the apparent strain rate-dependence is due to thermomechanical coupling with latent heat generation/absorption during phase transformation. |
