Abstract
The cyclic thermomechanical behavior of two-phase materials is investigated. Specimens of austenitic-ferritic duplex steels with a uniaxially anisotropic microstructure deform irreversibly even under pure thermal cycling conditions. In this work the combination of cyclic thermal and monotonic external loads is studied. The analysis reveals the necessity of incorporating the thermomechanical strain increment into the material law. The results are applied to predict the thermomechanical behavior of structural parts such as expansion joints.
