Abstract

The objective of the paper is to present safety analysis in an isotropic material disc fitted with a rigid shaft under the influence of thermo-mechanical load by using Seth’s transition theory. The rubber material disc must require higher angular speed to yield at the internal surface as compared to the copper material disc. Performance of the mechanical load places the copper disc on the safer side of the design as compared to rubber disc with temperature, because the radial stress is less for the rotating disc without temperature as compared to the disc with temperature, which leads to the idea of stress saving and minimizing the possibility of fracture of the isotropic rotating disc. Results are discussed numerically and depicted graphically.

Keywords: thermo-mechanical load, stresses, displacement, rubber and copper disc
