damage-rupture process zone at crack tip was surveyed with infrared thermographic sensor. Based on the irreversible thermomechanics theory, the dissipation law of deformation-heat effect during the whole process was found. Furthermore, the effect of thermoelasticity in the initial stage of extension was explained. Key words: thermomechanical coupling; irreversible thermomechanics; dissipation......
