These days there can be observed still increases requirement about products quality at keeping low price level. Such contending claims of market environment force producers in every branch of engineering industry to innovate their technological procedures and to process new progressive materials with specific utility properties. Regarding great development of numerical simulations there is not only use of computation methods but also qualitatively higher level of modeling technological processes where PCs behave as computational models on which it is possible to simulate also such processes which would be very difficult to carry out on the real part under operating conditions. Numerical simulations results are greatly influenced by knowledge and quality of input data. There are mainly boundary conditions which characterize simulated process, knowledge of the stress and deformation behavior of forming material and last but not least also selection of the proper computational model. For the most used computational models is material deformation behavior described only by static tensile test in combination with normal anisotropy coefficients. However for specific materials, thus also titanium alloys, is such characterization insufficient and is obvious that results from numerical simulations observed from this measurement do not agree with the real forming processes (mainly stamping). In this paper is described possibility to use advanced computational models for drawing process numerical simulation by software PAM STAMP 2G and method how to obtain input parameters for the material definition of the formed material. Results from the numerical simulation are compared with experiment ones.
