Stress Distribution

 With the rise in demand of materials for production, it's needed to style associate degree object specified consumption of fabric are often reduced for same operating conditions or load carrying capability are often increased for same consumption of fabric. during this paper, pressure vessel has been designed to face up to high internal pressure for same consumption of fabric. For this purpose, multilayer pressure vessel is made by shrink-fit of vessel, that has residual stress among it caused by pre-autofrettage, followed by autofrettage of the assembly. Thus, increase within the variety of layers will increase the quantity of the way to assemble and therefore this analysis is restricted to three-layered pressure vessel. doable ways in which to assemble the three-layered vessel for various autofrettage or reautofrettage p.c and radial interference for shrink-fit area unit mentioned during this paper. Considering these parameters as style parameters associate degreed maximization of fatigue life as an objective perform, improvement is administered by Genetic formula. For the optimum worth of style variables, stress distribution for the assembled pressure vessel at style pressure is studied. it's discovered that fatigue lifetime of every case is completely different with very little variation of most and minimum hoop stresses
