Abstract

Hole-drilling method is the most widely used method for measuring residual stresses. This method is performed using strain gage rosette attached to the surface of the studied components, through which we drill blind or through-hole. This paper is devoted to analyzing of influence of strain gage rosette on relieved strain. Our aim was to establish more accurately model of strain gage rosette, and examine its effect on hardening of the surface around the hole. For modeling by FEM was used strain gage rosette RY 21 made by HBM.
