Abstract:

A study was made of thermal stresses generated in a disk by a rotating heat source. The problem is treated within two-dimensional elasticity theory, and inertia effects as well as thermodynamic coupling are neglected. The solutions for the stresses and the temperature are obtained in the form of infinite series of elementary and Bessel functions. Relative to a coordinate system rotating together with the heat source, the solutions for the stresses and temperature separate into transient and non-transient parts, the decay of the transient solutions being relatively slow. Numerical results are presented, and the behavior of stresses and temperature is studied in some detail, particularly for points near the edge of the disk. Author
