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.

Hot forging of an Fe-Ni-Co alloy used for aeronautical purposes has been modeled using the commercial software ABAQUS™/Explicit in order to obtain all the mechanical and thermal information to proceed with piercing and ring rolling. The material used is a 909 Incoloy type super alloy and it is used for the energy generation industry. Information of the constitutive behaviour of the alloy was introduced into the package using experimental data from mechanical testing at different temperatures and strain rates. A thermo coupled analysis was carried out, temperature, stress and strain distributions were evaluated in order to use the results of the model for the further simulation of the ring rolling of the material.
