Mathematical, numerical and experimental investigation of mechanical effects oflow energy impact loading on hybrid composites

In this research, a mechanical model of nonlinear mass-spring and corresponding differential equations ofmotion derived from it, as well as the simulation of finite element method (FEM) of the dynamic effect of lowenergy impact on ۴ types of GLARE were performed, and the results obtained from the mathematical model andsimulation of finite element were compared with the experimental results. Comparison of mathematical model,finite element simulation results with experimental data, showed that the low energy impact response of thesemethods is in good agreement with experimental data.
