Multiple Impact of Composite Hyperbolic Shells: A Finite Element Approach

This chapter investigates the multiple impact responses of laminated composite shells using a finite element approach. The governing equations are developed based on eight-noded elements, with each node having five degrees of freedom. Time-dependent equations are solved utilizing the modified Hertzian contact law and Newmark’s time integration scheme. A parametric study evaluates the effects of factors such as impact location, velocity, and laminate configuration on the maximum contact force and plate displacements. Statistical analysis highlights differences in material performance between random multiple impacts and deterministic single impacts. This research makes a significant contribution to the study of composite materials by analyzing the response of laminated composite shells under multiple impact scenarios. This work also lays the foundation for further studies into the impact behavior of composites in more complex scenarios.
