The role of prototypes has increased considerably, especially functional prototypes, with the help of which the parts can be examined under the working conditions. Recently has been realised that the demand for functional prototypes and the use of built-in rapid prototypes in small series production and medical science have increased significantly. It became necessary to be able to decide whether the certain model can be used in its real load conditions in its application network. In more complicated cases even finite element analysis is need to be carried out. For the correct results at numerical simulation - assuming the exact knowledge of the loads and boundary conditions -the validated material properties also need to be known. The optical photostress method is a good method to validate the previously determined material properties.
