Abstract
This paper investigates the creep analysis of linear and non-linear distribution of SiCP content in therncylinder made of functionally graded material and subjected to internal pressure. The creep behaviourrnof the composite cylinder is described by a Norton’s Power law. The study reveals that for the linearrnand non-linear particle gradient, the radial stress decreases over the entire cylinder. By increasingrnParticle gradient in the FGM Linear and FGM Non-Linear Cylinders, the tangential stress increasesrnnear the inner radius but decreases toward the outer radius when compared with a similar cylinder butrnhaving uniform particle gradient. The magnitude of strain rates in functionally graded compositerncylinder reduces significantly in the presence of non-linear SiCP gradient along the radial direction
