复合材料帽型加筋板界面应力与失效模拟
INTERFACIAL STRESSES AND FAILURE SIMULATION OF COMPOSITE HAT-STIFFENED PANEL
摘要
Abstract
Based on CZM (Cohesive Zone Model),FEM model is built up to study the interfacial stresses and debonding failure of the composite hat-stiffened panel subjected to four-point bending.In the present model,the debonding failure of the adhesive layer between the skin and stiffener is considered by adding interface elements between the solid elements.The results indicate that:adhesive debonding is the main failure pattern of composite hatstiffened panel,shear stress has a major effect on the debonding of bondline,and the failure of the adhesive layer can largely decrease the load-carrying capacity of the structure and lead to more serious damage.关键词
