Thermomechanical coupling effect of PVC sheet with defects

摘要：

Thermomechanical coupling of PVC sheet with defects under uniaxial loading at different rates and different sizes of microbores was studied. The local temperature field of the dynamic damage-rupture process zone at crack tip was surveyed with infrared thermographie sensor. Based on the irreversible thermomechanics theory, the dissipationlaw of deformation-heat effect during the whole process was found. Furthermore, the effect of thermoelasticity in the initial stage of extension was explained.
