Abstract Stress analysis has been performed in an elastic-plastic rotating disk made of functionally graded material. Elastic-plastic stresses are calculated by applying the concepts of transition theory based on generalized principal strain measure using Eulerian finite deformation theory. The results obtained from the analysis are discussed numerically and depicted graphically for different geometrical parameters. It is observed that variable thickness and non-homogeneity have significant effects on the circumferential stresses in the functionally graded rotating disk. Keywords: elastic, plastic, rotating disk, pressure, functionally graded material, finite deformation |
