Abstract

Theoretical models of the behavior within the pseudoelastic hysteresis loop of shape memory alloys are presented. These models are considered in the analysis of the dynamic response of a cantilevered beam constrained by shape memory wires. Quantitative results of damping and shift in natural frequencies of the structure are presented, and the effect inner hysteresis loops have on structural dynamics are compared to those found experimentally. The results suggest the possibility of the existence of two trigger lines, one for loading and one for unloading, within the hysteresis loop, and a relationship between the trigger line angle and a maximum dissipation principle.
