Abstract : Methods for determining temperature distributions for cylindrical grains under various types of surface temperature variations were developed for the subsequent viscoelastic transient thermal stress analysis. These methods were verified by experiments performed on cylindrical grains with thermocouples cast in place. The viscoelastic thermal stress problem has been reduced for computer programming. Results of uniaxial thermal cycling experiments are presented. The effects of temperature on viscoelastic behavior have been determined experimentally and experimental results of failure tests on case-bonded grains are included.
