Thermal-mechanical analysis of metal forming based on meshfree method
A thermal-mechanical analysis of metal forming based on meshfree method is performed. During the coupled analysis, two independent sub-systems, I.e. the velocity field and temperature field are considered. The effect of deformation on temperature field is added into the temperature solution by the vector of heat flux generated by internal energy, and the effect of temperature on plastic deformation is considered by the flow stress at that temperature. The unknown function of temperature distribution is constructed using reproducing kernel approximation. Contours of the temperature field of a metal ring under compression are obtained. Using the thermal-mechanical coupling method, the results are compared with those obtained by FEM and experiment to verify the accuracy of the proposed method.
