Özet

A complete dynamic model is presented to study the response of smart hybrid composite structure embedded with shape memory alloy (SMA) wires subjected to low velocity impact. The analysis could be used to calculate the contact forces, the deflections, the velocities and the in-plane strains and stresses of the structure during the impact. The SMA wires were embedded within the layers of the composite laminate. The first-order shear deformation theory (FSDT) as well as the Fourier series method was utilized to solve the governing equations of the composite plate analytically. The interaction between the impactor and the plate was modeled with the help of two degrees-of-freedom system, consisting of springs-masses. The Choi's linearized Hertzian contact model was used in the impact analysis of the laminated hybrid composite plate. A computer program was developed based on the analysis. The results of calculations of the program were compared with the existing paper results. An excellent agreement was seen between the comparisons. The effect of the volume fraction of the SMA wires on the contact forces, the deflections, the velocities and the in-plane strains and stresses of the structure during the impact Were Studied. It was seemed that embedding the SMA wires within the layers of the traditional laminated composite plates Would improve the Impact resistance Of the Structures remarkably.
