ANALYSIS AND EXPERIMENTAL VALIDATION OF COMPOSITE LAP JOINT WITH CRACK FOR AEROSPACE APPLICATIONS

Composite materials have made way to several different fields, including aerospace structures, under water 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 single lap joint with crack in-built in adhesive layer. In several different applications and also for joining various composite parts together, by using epoxy adhesives. Modeling and static analysis of 3D Models of lap joints were carried out and compared for two different composite materials. 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 to be found.
