| Abstract: | The fundamental equation of nonlinear thermoelastically coupled vibrations is derived from the exact equations of the elastcity theory. Force and thermal boundary conditions are analysed. For example, the all-edge clamped plate and tie all-edge simply supported plate and plate with mixed edge conditions are dealt with. The mechanism of the thermoelastic coupling effect on the amplitude and the frequency is presented. It is valuable for the theory and applications of the plate dynamics. |
