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 damagerupture process zone at crack tip was surveyed with infrared thermographic sensor Based on the irreversible thermomechanics theory the dissipation law of deformationheat effect during the whole process was found Furthermore the effect of thermoelasticity in the initial stage of extension was explainedFoundation item Project10672191 supported by the National Natural Science Foundation of China Project06JJ2059supported by the Provincial Natural Science Foundation of Hunan China ProjectKF0607 supported by the Key Laboratory of Low Dimensional Materials and Application Technology Xiangtan University Ministry of Education China
