Analytical estimation of low velocity impact force history on composite laminates using different models

Abstract- In this paper, contact force history in low velocity impact on laminated composite with simply-supported boundary condition, using three different spring-mass models is investigated, analytically. Using two degree of freedom spring-mass model, modified spring-mass model and static model, the dynamic force of impact is calculated and then imposed on impacted place in the plate. To insure the accuracy of the present models, the contact force history validated with experimental results available in literature. The results indicated that changing the mass of impactor and velocity has significant effect on impact response and three models are in a good agreement with each other. Keywords - , , , , .
