Composite Patch Bonded Repair Simulation and Optimization of the Lap Joints

摘要：

　　In this paper,the finite element method is applied to optimize the stress distribution of the adhesively bonded composite patch for repairing of a cracked metal plate.A three-dimensional finite element model was created and simulated,a finite element procedure is programmed to find the optimized parameters of the composite patch,and the optimized parameters are listed for convenient application.The simulated result shows that the directions of the plies and the distance between the lap joints could affect the adhesive stresses distribution greatly,and compared with the single lap joint case,the maximum shear stress of the recommended multi-joints case could reduce more than 80%.
