Material Parameter and Effect of Thermal Load on Functionally Graded Cylinders

Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2015, Vol 5, Issue 4

Abstract

The present study investigates the creep in a thick-walled composite cylinders made up of aluminum/aluminum alloy matrix and reinforced with silicon carbide particles. The distribution of SiCp is assumed to be either uniform or decreasing linearly from the inner to the outer radius of the cylinder. The creep behavior of the cylinder has been described by threshold stress based creep law with a stress exponent of 5. The composite cylinders are subjected to internal pressure which is applied gradually and steady state condition of stress is assumed. The creep parameters required to be used in creep law, are extracted by conducting regression analysis on the available experimental results. The mathematical models have been developed to describe steady state creep in the composite cylinder by using von-Mises criterion. Regression analysis is used to obtain the creep parameters required in the study. The basic equilibrium equation of the cylinder and other constitutive equations have been solved to obtain creep stresses in the cylinder. The effect of varying particle size, particle content and temperature on the stresses in the composite cylinder has been analyzed. The study revealed that the stress distributions in the cylinder do not vary significantly for various combinations of particle size, particle content and operating temperature except for slight variation observed for varying particle content. Functionally Graded Materials (FGMs) emerged and led to the development of superior heat resistant materials.
