analysis of influence of Strain gage rosette on Relieved Strain
American journal of mechanical engineering, 2013Co-Authors: Patrik Sarga, Peter Senko, Frantisek TrebuňaAbstract: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.

measurement of in plane residual stresses varying with depth by the interferometric Strain slope rosette and incremental hole drilling
Journal of Engineering Materials and Technology-transactions of The Asme, 2003Co-Authors: Tana Tjhung, Keyu LiAbstract:A new experimental method utilizing the Interferometric Strain/Slope Rosette (ISSR) and incremental hole-drilling is applied to measure in-plane residual stresses which vary with depth. For each depth increment, the ISSR measures three Relieved Strain components and two Relieved slopes at point near the hole edge. Adapting the classical Integral Method to the ISSR, and incorporating a Tikhonov regularization scheme, stabilized residual stress solutions are back-calculated from the measured deformations. This paper describes the measurement principle of the ISSR, the derivation and numerical calculation of the ISSR hole-drilling coefficients, and the methodology used to back-calculate and regularize the residual stress solution, A verification test on a thin-plate with a through-hole, and residual stress measurements performed on a shot-peened Titanium-alloy block, are presented and discussed.
