Abstract

In this paper, the problem of low-velocity transverse impact on a sandwich panel with FUNCTIONALLY GRADED CORE has been considered. The interaction between the impactor and the panel is modeled with the help of a system having two-degrees-of-freedom consisting of springs-masses. In order to determine the contact force history, a numerical procedure is employed based on improved higher-order sandwich plate theory. Shear deformation theory is used for the face sheets while three-dimensional elasticity theory is used for the core. For the first time effect of consideration of in-plane shear stress and normal stress in the core is considered. Displacement components in the core are assumed to vary with a polynomial function with unknown coefficients. Results indicate that use of the FG core can reduce deflections and increase maximum of contact forces.
