The key aim of the project is to support the activity of designers and product engineers in the phase of production of automobile components from tailored blanks, focused on the abatement of emissions in production and car traffic by decreasing the weight of particular components of car body. The ambition of the project is to imply scientific knowledge obtained from numerical and experimental methods to the proposals of modified standard procedure of validation of the virtual methods. The numerical methods in combination with the experimental methods present a very strong tool for supporting the activity of designers and product engineers and allow reacting more effectively to the changes in the technological process, allow decreasing the experimental works, which lead to increasing quality, reliability and competitiveness of the firms that are producing components of automobiles from tailored blanks. The accuracy and reliability of prediction of simulation results depends on the accuracy of the material model, and accuracy and completeness of material data. On the base of results of experimental and virtual tests, prediction models of an index of functionality, formability and weldability will be proposed. A model of multi-criteria optimization of working properties of the components, which will lead to the increase of competence of engineers in process of innovation, proposal and production of new components of car bodies, will be proposed.
