Paper Abstract

The influence of a technological surface layer on the strength of machine element is confirmed by an increasing number of theoretical and numerical investigations. However, due to the use of modified finite elements in the small region of layer, as well as implementing the variation of hardening moduli in the material model, the experimental verifications of FEM results is strongly required. In this study, automated grating interferometry is applied for in-plane u and v displacment maps determination. Experimental results are compared with numerical analysis performed for the sample with and without surface layer. The increase of the strength of machine parts with the technological surface layer is confirmed experimentally. The possibility of interactive application of experimental results in order to improve numerical FEM model is discussed.
