Abstract:The finite element method(FEM) is used for simulation of piercing process of the tube in Mannesmann mill.The numerical model is described and takes into consideration for example thermal phenomena present in metal during forming.The simulation results visualize dynamic distributions of equivalent strains,equivalent strain rates and temperature,especially inside the workpiece.On the basis of the basic parameters,the phenomenon in the piercing process is analyzed.The model was verified by comparing the values of calculated force parameters of the piercing process and those measured in laboratory conditions.
