关 键 词：thermomechanical coupling irreversible thermomechanics dissipation thermoelasticity effect
摘 要：正Thermomechanical coupling of PVC sheet with defects under uniaxial loading at different rates and different sizes of microbores was *** local temperature field of the dynamic damage-rupture process zone at crack tip was surveyed with infrared thermographic *** on the irreversible thermomechanics theory,the dissipation law of deformation-heat effect during the whole process was ***,the effect of thermoelasticity in the initial stage of extension was explained.
