WebbThermomechanical Analysis (TMA) • The tests are run in a heating mode at a desired heating rate and temperature range of interest. • Probe displacement profiles are subsequently analyzed in terms of coefficient of thermal expansion, softening and melting temperatures, and glass transition temperatures. WebbThermomechanical coupling between temperature and stress fields modifies the heat equation considered for nonequilibrium energy transport. In this case, energy absorbed by the irradiated material is partially dissipated through heat transfer and partially used for thermal expansion of the substrate material.
