Abstract

In development of new metal forming procedures it is important to know process parameters such as forming force, deformation work, stress scheme etc. Theoretical analysis is usually not enough accurate method because of numerous simplifications and assumed boundary conditions that cannot accurately describe the real situation. Beside numerical simulations, the only better method is real physical modelling by scaling down (or up) real dimensions. Similarity theory connects model, real product and process parameters. This paper associates finite element modelling and similarity theory, in order to easily and quickly determines the forming force level for the real product. Model is numerically created and its adequacy is tested by both – similarity theory and finite element modelling.
