Abstract

The analysis of sheets deformation and corresponding knowledge of their elastic and plastic properties has a great meaning by their following processing. The aim of this contribution is to focus on the description of use an optical ESPI system Q-300 Dantec Dynamics by investigation of elastic deformations of sheets with stress concentrators in a form of notch. The results obtained experimentally using mentioned measuring device were verified numerically in program Ansys Workbench. The paper briefly describes the methodologies of both, experimental and numerical, types of modeling.
