Abstract

In the present paper, nonlinear dynamic analysis of low-velocity impact of rectangular COMPOSITE PLATEs reinforced by SMA strips is investigated and the effects of the instant phase changes and the local and istatantaneous non-uniform distribution of transformation of the austenite to martensite phases and vice versa is considered, for the first time, implementing a written user defined material subroutine code in the ABAQUS/EXPLICIT finite element analysis code. In contrast to the available models which have used the approximate plate theories, a 3D finite element simulation is utilized for extracting the impact responses based on the elasticity theory. Finally, effects of different parameters such as the in-plane preloads, eccentricity, and indenter energy on the impact responses of the hybrid COMPOSITE PLATE are investigated. The simulation results indicate that the SMA can absorb a remarkable portion of the stored impact-induced strain energy due to the super elastic and hysteretic natures of the SMA material, which results in increasing impact strength of the COMPOSITE PLATE and decreasing the damage caused due to the impact. Moreover, results show that in the cases of the eccentric impact and presence of the tensile preloads, the contact force increases due to the less movability of the impacted point of the plate; a fact that may lead to higher damages.
