Creep evolution analysis of rotating cylinder made of exponentially graded material (EGM) abstract
Time dependent creep response of a hollow rotating cylinder made of exponentially graded material (EGM) is investigated. The cylinder is subjected to an internal pressure, a distributed temperature field and a centrifugal body force. The EGM material properties are assumed to be exponentially graded along radius. An analytical solution followed by the method of successive approximation has been employed to obtain history of stresses during creep evolution of the EGM rotating cylinder. The material creep behavior is defined by the Bailey-Norton time-dependent creep law. It has been found that the material in-homogeneity exponent has a significant effect on temperature distribution andcreep response of the EGM cylinder. It has also been concluded that radial, circumferential, axial and effective stresses are decreasing with time due to creep evolution.
