Abstract

The process of defect evolution is complicated which cuts across micro-, meso- and macroscale levels, and should be inherently characterized by its rheology and dissipation. Experiments of heat generation induced by any irreversible deformation in the tensile failure process of thermoplastics with prefabricated defects have been made in details. The initiation and evolution laws of the local temperature field near defects are observed and recorded with infrared photography, and then preliminarily analyzed. It is shown that the heat generated during defect evolution is significant in our experiments and comprises some 25 to 70 per cent of the of external work, so its contribution to the failure of materials is not negligible. Considering the micro- and mesoscopic characters of deformation, a preliminary and qualitative explanation to the cooling and heating phenomena observed in the experiments is also presented in this paper.
