Abstract

In the process of design of machines and equipment high attention has to be given to structural notches, defects of materials and surface quality, because they have high impact to their fatigue strength. In the paper is presented proposal of methodology concerning deformation analysis near stress concentrators by using strain gages. The experimental measurement was realized on bended U-shape specimen with notches. The results gained by experimental measurements were verified by numerical modelling by the finite element method.
