Abstract

The secondary stage creep deformations and creep stress in a thick walled spherical vessels made of functionally graded composites has been obtained in the present study. The spherical pressure vessel chosen for the investigation is subjected to internal and external pressure under constant temperature field. The material of the vessel is incompressible and volume constancy condition was assumed. The creep behaviour of material is governed by threshold stress based creep law. The study reveals that for linear variation of reinforcement and assumed pressure ratio the compressive value of radial stress reduces with increase in pressure ratio from 2 to 5 over entire radial distance. However, the longitudinal stress remains compressive at inner radius, however, the value become tensile for pressure ratio 3, 4 and 5.
