Abstract
Most current applications of shape memory alloys (SMAs) make use of static properties. However, the hysteresis in the load-deformation behavior also constitutes a very efficient damping mechanism in vibrational applications. The paper studies the SDOF vibration of a rigid mass suspended by a thin-walled SMA tube under torsional loading. The behavior is analyzed for the cases of quasiplasticity and pseudoelasticity on the basis of an improved version of the Mueller-Achenbach model. To illustrate the damping capacity and the nonlinear vibration characteristics, both, free and forced vibration cases are considered.
