In this paper, analytical modeling and numerical simulation of sandwich panel behavior with metal foam core under low impact impact are presented and how the formation and development of impact defects in impact loading conditions in three samples with different face sizes Taken, checked. Multi-layer sandwich panels are made of epoxy carbon and the core is also made of metal foam. Analytical modeling of low speed shock load on sandwich panels, using mass model and two-degree free spring, has

The spring stiffness of the contact site, and the bending and shear spring stiffness of the sandwich panel are calculated, the values of which change over time. To solve the equations of motion, the exact solution method has been used and the radius of the affected area is calculated using energy equations. In the next section, simulation of low speed impact on sandwich panels with metal foam core is done in three samples of different sizes in Abacus software, so that we see how to create and develop defects in sandwich panels. In the next section, we have examined the results and compared the numerical solution and analytical simulation, which confirms the process of research and this has been proven to be important.
