Elastic–plastic stresses in rotating connection disk under temperature rise and transmitted torque

A connection disk rotating at constant speed under temperature rise and transmitted torque at the inner and outer clamped edges is modeled using a nonlinear elastic–plastic stress–strain relation, and the elastic–plastic effective stress in Von Mises yield criterion is obtained efficiently by the finite difference method with a closed-form initial predicted value. Effects of rotational speed, edge temperature rises, transmitted torque and their couplings on the elastic–plastic stresses of the connection disk are studied. It is seen that the effective stress increases generally with the edge temperature rises, and the outer edge temperature rise increases the maximum effective stress more remarkably than the inner edge one; the maximum elastic–plastic effective stress occurs at either the inner edge or outer edge.
