The finite element method (FEM) is used for simulation of the tube piercing process in Mannesmann mill. The numerical model
is described with taking into consideration thermal phenomena in metal during forming. The simulated results visualize dynamic
distributions of mean stresses, temperature, velocity and shear stresses, especially inside the workpiece. On the basis of
the basic parameters, the phenomenon in the piercing process is analyzed. The model is verified by comparing the values of
calculated force parameters of the piercing process and those measured in laboratory conditions. 相似文献
