Discontinuous Yield and Large Deformation Analysis on Rotating Disk Based on J2 Deformation Theory

Abstract

Rotating discs are used widely as important structural elements in mechanical engineering. In order to obtain an optimal structural design, it is necessary to estimate the angular velocity and the stress distribution of a rotating disc in fully plastic state. So J2 deformation Theory is used for large deformation analysis of axisymmetric rotating disk. The bursting speed of rotating disk, the stress distribution at instability and analysis on the elastic-plastic interface of rotating disk are studies in detail.
