In this paper, analytical modeling and numerical simulation of sandwich panel behavior with metal foamcore under low impact impact are presented and how the formation and development of impact defects inimpact loading conditions in three samples with different face sizes Taken, checked. Multi-layer sandwichpanels are made of epoxy carbon and the core is also made of metal foam. Analytical modeling of low speedshock load on sandwich panels, using mass model and two-degree free spring, has been used to calculatethe contact force. The spring stiffness of the contact site, and the bending and shear spring stiffness of thesandwich panel are calculated, the values of which change over time. To solve the equations of motion, theexact solution method has been used and the radius of the affected area is calculated using energyequations. In the next section, simulation of low speed impact on sandwich panels with metal foam core isdone in three samples of different sizes in Abacus software, so that we see how to create and develop defectsin sandwich panels. In the next section, we have examined the results and compared the numerical solutionand analytical simulation, which confirms the process of research and this has been proven to be important.
