Elastic-plastic stress distribution in a rotating hyperbolic disk with rigid inclusion. (English) Zbl 0899.73269

Summary: We study the elastic-plastic stress distribution in a rotating hyperbolic annular disk mounted on a circular rigid shaft. The presented exact solution is based on the usual assumptions of plane stress, Tresca’s yield condition, its associated flow rule and linear strain hardening material behaviour. According to the present analysis, the plastic core consists of three parts with different forms of the yield condition. The theory is illustrated by numerical results. The results show that the plastic flow and maximum stresses are influenced by the thickness parameter.
