Abstract

Composite materials have made way to several different fields, including aerospace structures, under wa ter vehicles, automobiles and robot systems etc . Due to the high strength they are widely used in the low weight constructions and also used as a suitable alternative to metals. ANSYS FEA tool has been used for stress distribution characteristics of variou s configurations of do uble riveted single lap joint with three joining methods namely bonded, riveted and hybrid. In several different applications and also for joining various composite parts together, they are fastened together using adhesives or Mec hanical fasteners. Modeling and static analysis of 3D Models of joints such as bonded, riveted and hybrid were carried out and compared for two different composite materials. The results are found in terms of total deformation, vonmises stress, sh ear stres s, and normal stress for stress distribution and strength analysis. The present study deals with the analysis of single lap joint subjected to tensile load and the stress distribution in the joint members under various design conditions are found.
