筋条形状对复合材料加筋壁板 低速冲击动态响应的影响
Effect of Stiffener Shape on Low-Velocity Impact Behavior of Composite Stiffened Panels
摘要
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.关键词
