Abstract: Thermoelastic analysis for a rotating circular HSLA (high strength low alloy) steel plate with variable thickness, which is placed in a temperature field, and subjected to a mechanical load is presented. Based on the von Karman equation and classical thin plate theory, the nonlinear governing equations for the mid-plane displacements of the rotating circular HSLA steel plate are obtained by using the Hamilton variation principle. The displacements and rotation angle are discretized in space and time domains by utilizing the finite difference method and Newmark method, and the whole problem is solved by the iterative method. Numerical results show that the geometric shape, angular speed, mechanical load and temperature field all have great influence on the thermoelastic behavior of the rotating circular HSLA steel plate.
