Abstrakt :The main goal of this paper is verification of accuracy of ESPI strain sensor Dantec dynamics Q-100. ESPI is the digital holographic interferometry method for measuring small displacements and deformations. There is necessary to consider the isotropic material properties for stress calculations using the ESPI systems. All stress measurements were performed on simple shape specimens subjected to tension and bending. The results of experiments performed on the tensile testing machine Testometric has been confronted with numerical results.
