| dc.description.abstract | A study of the dynamic behavior of polycrystalline Shape Memory Alloys (SMA) under impact loading was proposed. The purpose of this study was to obtain basic understanding of the thermomechanical response of SMAs under dynamic loads, described by the numerical solution of initial boundary value problems of a semi- infinite, one-dimensional SMA rod subjected to impact loading. Special focus was placed on the initiation and propagation of material phase transformation due to the presence of stress waves, as well as on the influence of thermal (latent heat) effects on such phase transformation. The initial boundary value problem of impact loading was numerically solved through the implementation of appropriate finite difference and finite element analysis techniques. This procedure allowed the determination of dynamic phase transformation properties and the estimation of the propagation velocity of the phase transformation front. Finally, a comparison of the obtained numerical results to existing analytical predictions, and experimental measurements was performed validating the obtained data for the determination of constitutive relations for SMAs as well as a framework for future analysis of SMAs through numerical procedures. | en |
