Thermoelasticity
Many important stress analysis problems involve structures that are subjected to both mechanical and thermal loadings. Thermal effects within an elastic solid produce heat transfer by conduction, and this flow of thermal energy establishes a temperature field within the material. Most solids exhibit a volumetric change with temperature variation, and thus the presence of a temperature distribution generally induces stresses created from boundary or internal constraints. If the temperature variation is sufficiently high, these stresses can reach levels that may lead to structural failure, especially for brittle materials. Thus, for many problems involving high temperature variation, the knowledge of thermal stress analysis ...
