Abstract

In this paper, the effect of low-velocity lateral impact of a small and large mass on dynamic response of a cantilever fiber metal laminate (FML) composite plate is studied using an analytical-numerical method. The interaction between the impactor and the FM L plate is modeled using a two degrees-of-freedom system consisting of springs masses and finite element software (ABAQUS). The impact force function is determined analytically and then the response is computed using the finite element software. The correctness of the obtained results is compared and verified with the previous studies. The results indicate that if a small mass is impacted on a FML plate having cantilever or simply supports, parameters like the mass and velocity of the impactor, mass of the plate (target), orientation of composite fibers and the natural frequency of plate have nearly no effect on impact force and plate deflection. Whereas, for a large mass impactor, the same parameters have significant effect on the dynamic behavior of the plate.
