Plastic stresses in a thin rotating disk made up of piezo-electric material are determined. Tresca’s yield condition with nonlinear strain hardening measure has been assumed to derive the nonlinear differential equation. The shooting method has been used to evaluate the graphical results for radial and circumferential stresses. Also, it has been found that piezoelectric material with less angular speed is more suitable material for a rotating circular disk as it gives less circumferential stress.
