Assuming a "tensioned" circular saw in use, a theoretical analysis is performed to investigate the thermoelastic field and dynamic characteristics in a rotating annular disc that is subjected to the temperature and in-plane plastic strain distributions. Based on the plate bending theory, the governing equations for the axisymmetric in-plane behavior due to the thermal load, plastic strain, and rotation and the resulting unsymmetric anti-plane behavior are derived. Then, the solution of in-plane forces is obtained and the modal analysis of the disc is performed. Numerical examples are shown to investigate the thermoelastic field in the disc and the effect of the distribution of the plastic strain on the dynamic characeristics.
