混合垫片对称性对复合材料单搭接接头力学性能的影响
Effect of Hybrid Gasket Symmetry on Mechanical Properties of Composite Single-lap Joints
摘要
Abstract
The influence of hybrid gasket symmetry on the tensile stiffness and peak load of composite single-lap joints is studied by finite element analysis and experimental comparison.The displacement value of the joint under dynamic load is observed by video extensometer,and the influence of hybrid gasket symmetry on the fatigue life and hole deformation of the joint is studied.The results show that the symmetry of the hybrid gasket has little effect on the tensile limit load and tensile stiffness of the joint,the surface of composite materials using asymmetric gaskets to fill the gaps,especially on the thick side of the liquid gasket,however,is prone to strain concentration areas.After bearing dynamic load,the hole deformation of the joint has asymmetry,and when the asymmetric hybrid gasket is used for gap filling,the asymmetry of the structural hole deformation is stronger.关键词
