Paper Abstract

In this paper, we conduct finite element analysis of a pseudoelastic SMA wire with curved shape, which is designed as a spring component in the base isolation devices. A simplified constitutive equation is implemented with the finite beam elements based on the updated Lagrangian formulation to deal with the geometric and material nonlinearities of the SMA wires. The simulated deformation shapes and the force-displacement characteristics are compared with the measured results.
