Prediction of impact and fatigue life behavior of FML by finite element and mathematical simulation

In this research, a mechanical model of nonlinear mass-spring and corresponding differential equations of motion derivedfrom it, as well as the simulation of finite element method (FEM) of the dynamic effect of low energy impact on ۴ typesof GLARE were performed, and the results obtained from the mathematical model and simulation of finite element werecompared with the experimental results. Comparison of mathematical model, finite element simulation results withexperimental data, showed that the low energy impact response of these methods is in good agreement with experimentaldata.
