Effect of Stiffener Shape on Low-Velocity Impact Behavior of Composite Stiffened Panels

摘要

摘要: 针对复合材料加筋壁板的抗冲击问题，着重考虑筋条形状对其冲击动态响应的影响。通过局部细化的方法分别建立T型、工字型和帽型筋条的复合材料加筋壁板的有限元分析模型，采用黏结接触模拟层与层之间的界面，分析了3种筋条形状的复合材料加筋壁板在低速冲击下的动态响应和损伤情况。根据数值计算结果发现：结构的动态响应与冲击位置的刚度密切相关，T型和工字型筋条复合材料加筋壁板在冲击位置以外的区域发生翘曲；此时T型和工字型筋条的基体拉伸损伤不仅形状相似，而且损伤面积相近；蒙皮与筋条界面相邻两层的铺层角影响分层损伤的面积。

Abstract: In this research, we focused on the effect of the stiffener shape on the dynamic response of composite stiffened panels.We first established the finite element analysis model for composited stiffened structures with 3 kinds of stiffeners using the local refinement with the interface between the layers simulated by bonding interface, and then analyzed the dynamic response and the delamination damage of these composite stiffened panels.According to the results of the numerical simulation, it is found that the dynamic response is closely related to the structure stiffness, the composite stiffened panels with T-shaped and I-shaped stiffeners are warped in the region beyond the impacted part of the panels, and their damage distribution and damage area are similiar.The results also show that the layer angle of the two layers adjacent to the surface of the skin and the stiffener affects the area of the delamination damage.
