Multiple impact analysis of GLAss REinforced aluminum laminates (GLARE)

In the present study multiple impact response of GLARE has been investigated analytically. Governing equations are derived based on laminate theory and Hamilton’s principle. The Hertzian contact law is employed to capture contact force history and other impact characteristics. The nonlinear system of equations is derived based on Ritz approach and solved using the fourth order Rung-Kutta method . The validity of the present model is demonstrated by good agreement of comparisons between its predictions and results in the literature
