THERMAL STRESS ANALYSIS BY ENERGY METHODS,
Abstract
Ann energy analysis is used to obtain thermal stresses in a structure subjected to temperature variation. After structural idealization--the application of redundants between the specified adjacent structural elements--the temperature of each element is applied. With the redundants missing, each element freely expands; however, the confinements generating thermal stress are calculated by use of Castigliano's minimal energy theorem and with the aid of a digital computer. Temperature stresses due to dissimilar materials are also calculated by this method. Various materials are combined in an attempt to reduce the thermal stress. In particular the alpha delta T product of the various members is studied. (Author)
