Analysis of Shape Memory Alloy Hybrid Composite Plates under Low Velocity Impact

Abstract

This paper presents the analysis of smart hybrid composite plate with embedded shape memory alloy (SMA) wires subjected to low-velocity impact. The SMA wires were embedded within the layers of the composite laminates and the numerical calculation was used in the impact analyses of the laminated hybrid composite plate. The laminated plate theory, first-order shear deformation theory and minimal potential energy principle was utilized to solve the governing equations of the hybrid composite plate analytically. Energy absorption of hybrid composites can be successfully analyzed using analysis of variance (ANOVA). The results indicated that temperature effect is significant during the transition phase and SMA can effectively improve impact-resistance of the hybrid composite laminated plate. In addition, this hybrid structure is an advanced design concepts that can strengthen the impact resistance capability and enhance the carrying loading efficiency of the structure.
