| Abstract Scope |
In this talk, the influence of boundary conditions and discrete crack spacing on simulation results of thin composite laminates subjected to a low-velocity impact will be presented. This work aims to specifically investigate the force displacement behavior and damage development on the laminate. Discretely spaced zero-thickness cohesive elements are used to model the inter-ply and intra-ply damage on the laminate. Current results have shown that force displacement response can vary significantly if the roller supports are modeled as rigid with perfect contact conditions. To emulate the physical test compliance, the top roller is connected to spring elements while the bottom roller support remains as a fixed rigid body. Sensitivity analysis on the stiffness of the spring elements is performed to analyze its influence on the response of the plate by studying the development of membrane stresses. The outcome of this study will highlight the importance of proper boundary conditions modeling on problems related to low-velocity impacts. Furthermore, the influence of crack spacing in discrete crack modeling on force response, splitting and delamination will be presented. |
