Dynamic Response of Smart Hybrid Composite Plate Subjected to Low-Velocity Impact

In this article, the response of rectangular smart hybrid composite plate subjected to low velocity impact is studied and the effect of some geometrical and material parameters on the response of the composite plate embedded with shape memory alloy (SMA) wires is investigated. The interaction between the impactor and the composite plate is considered in the impact analysis. The SMA wires are embedded within the layers of the composite laminate. The effect of the SMA wires on contact force history, deflection, in-plane strains and stresses of the structure was studied. The classical first-order shear deformation theory (FSDT) as well as the Fourier series method is utilized to solve the governing equations of the composite plate analytically. The interaction between the impactor and the plate is modeled with the help of two degrees-of-freedom system, consisting of springs-masses. The Choi's linearized Hertzian contact model is used in the impact analysis of the laminated hybrid composite plate. The simultaneous application of the FSDT, Fourier series method, springs-masses and Choi's linearized contact model helps to get a complete model and more accurate result and save computational time and effort for the analysis of the composite structures subjected to the transverse impact. The results indicated that some of the geometrical and material parameters like the volume fraction, the orientation and the through thickness location of the SMA wires, the longitudinal to transverse elastic modulus ratio of the plate and the material type of composite medium are some of the important factors affecting the impact process and the design of the structures.
