Adaptive Tunable Vibration Absorber using Shape Memory Alloy

This study presents a new approach to control the nonlinear dynamics of an adaptive absorber using shape memory alloy (SMA) element. Shape memory alloys are classified as smart materials that can remember their original shape after deformation. Stress and temperature-induced phase transformations are two typical behaviors of shape memory alloys. Changing the stiffness associated with phase tran...

Finite element simulation of a self-healing shape memory alloy composite

A self-healing, metal matrix composite reinforced by shape memory alloy wires is simulated using finite element analysis. A one-dimensional constitutive model for SMA behavior is implemented as a user-defined truss element in ABAQUS. The matrix is brittle and a mode I crack is allowed to propagate through the specimen upon loading. During the loading process the wires undergo a martensitic phas...

Finite Element Modelling and Simulation of Phase Transformations in Shape Memory Alloy Thin Films

A unified variational framework and finite element simulations of phase transformation dynamics in a shape memory alloy thin film are reported in this paper. The computational model is based on an approach, which combines the lattice based kinetics involving the order variables and nonequilibrium thermodynamics. Algorithmic and computational issues are discussed. Numerical results on phase nucl...
