| Abstract Scope |
A mean-field approach (“β rule”) is developed for solid-state transforming materials and used to simulate the mechanical response of a high-temperature shape memory alloy. As a reference, full-field simulations using a representative volume element (RVE) and a crystal plasticity finite element model (CPFEM) are carried out. Results show that the β rule is able to predict the overall response of the material for various cases, such as actuation and superelasticity. This texture-sensitive approach allows to obtain anisotropic responses while keeping a high level of accuracy and reducing the computational cost. |
