THE FINITE ELEMENT ANALYSIS OF HEAT FIELD OF METAL SHEET DURING ELASTIC-PLASTIC DEFORMATION

The temperature distribution all over the metal thin sheet in the process ofelastic-plastic deformation was evaluated by the finite element analysis.With anassumption of almost lack of variance in thermal conductivity during less deforma-tion,the results of the heat field calculated from the finite element analysis usingKelvin's equation of thermal conductivity is in better agreement with that surveyedby an infrared camera.This calculation seems to be available for the thermal effectcaused by elastic-plastic deformation.
