Thermal ratcheting is the cyclic growth of a structure that is subjected to successive cycles of heating and cooling. The mechanism of thermal ratcheting in a simple two-element assembly is investigated. The conditions required for nonratcheting captive thermal cycling and for ratcheting cyclic growth are defined and a method is developed for computing the magnitude of the plastic strains and the cyclic growth.
