Paper Abstract

Introducing an interaction energy in the free energy function, the first two of the present authors proposed a 1D pseudoelastic model of shape memory alloys. The model has been demonstrated to represent qualitatively well some complicated experimental data on stress-strain-temperature relationships. To study the effect of large hysteresis due to pseudoelasticity of the alloys on their vibrational behavior, we carry out numerical simulations of vibration of a simple mass-spring system connected with a prestrained shape memory alloy wire whose constitutive equation is expressed by the present authors' pseudoelastic model.
