• OS0911 Finite Element Analysis of Transformation and Plastic Deformation in Shape Memory Alloy under Cyclic Thermomechanical Loadings

抄録

Shape memory alloys are known to exhibit shape memory effect and pseudo elastic effect. The alloys show two-way shape memory effect which is spontaneous deformation during thermal cycling without applied stress after appropriate thermomechanical cyclic loading. In this study, a polycrystalline finite element method which is able to take into account plastic slip and martensitic transformation is used to analyze the stress strain-temperature behavior under cyclic thermomechanical loading. Numerical results show that the origin of two-way shape memory effect is the local stress field induced by accumulation of plastic strain during thermomechanical cyclic loading.
