In an ordinary, uniaxial, elevated temperature creep test inaccuracy arises from various sources. One such source of inaccuracy is eccentricity of loading which has been reported in WADC TR 59-78. Another source, presented herein, is thermal stress considered in conjunction with its influence upon the creep rate.nIn this report the author calculates the thermal stresses induced in cylinders and plates by non-uniform surface temperatures. The relations of thermal stresses to creep are then determined for cylindrical and sheet creep specimens. These relations are expressed mathematically for sinusoidal and square wave surface temperature gradients. Numerical examples are presented and discussed.
