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. http://pubs.sciepub.com/ajme/4/7/23/ajme-4-7-23.pdf stress concentrator tensometry finite element method strain gage
