Abstract
In this paper, the low velocity impact response of sandwich panels with composites face sheets and aluminum based corrugated cores is modeled with numerical simulation, and the amount of energy absorption, contact force, deformation of the impact area and dimensions of the damage area are calculated and compared with experimental results. Sandwich panels with composite face sheets reinforced with carbon fibers and glass fibers and corrugated aluminum-based cores are in square, trapezoidal, arched, sinusoidal and triangular shapes. Through numerical simulations ten examples have been analyzed. Dimensions and weights of face sheets and cores of the samples are the same. The obtained results show that in the sandwich panel with trapezoidal and square corrugated cores, the contact force is applied to a larger area and the energy absorption and dimensions of the damage area are greater. Also, sandwich panels with arc and sinusoidal wave shape cores have the greatest displacement at the point location compared to other sandwich panels.
