Abstract

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 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.

Keywords
