Development and research of products is mostly done in virtual environment, where simulations take place based on mathematical-physical models and product properties, which also include elasto-plastic material properties. The goal of this master thesis is to check if we can identify these parameters using digital image correlation. We made real experiments with the tensile testing machine and virtual experiments with FEM analysis. Some of the included topics are also sensitivity of parameter identification and the method of inverse identification. Throughout the thesis, we confirmed the material parameter identification with the help of digital image correlation.
