Webb18 September, 2001. Shape memory alloys (SMAs) exhibit a very complex material behavior. Depending on load and temperature a number of unusual effects like shape memory or superelasticity may be observed in these metals. These phenomena are due to a martensite-austenite phase transition in the crystal lattice and to martensitic twinning. WebbIn this paper, the superelasticity effects of architected shape memory alloys (SMAs) are focused on by using a multiscale approach. Firstly, a parametric analysis at the cellular …

In this paper, a methodology based on three-dimensional (3D) finite element procedures is developed and used to simulate the superelastic behavior and the shape memory effect (SME) of shape memory alloys (SMAs). A 3D constitutive model for SMAs is implemented as a user defined subroutine for the finite element code ABAQUS.
