estimation of residual stress field uniformity when using the ring core method
Advanced Materials Research, 2014Co-Authors: František Menda, Patrik Sarga, František TrebuňaAbstract:The evaluation of residual stresses using Ring-Core method requires complex analysis of the acquired strain values. The development is based on ASTM Standard E837-08 for hole-drilling method, but the specific approach for Ring-Core is needed. The input data sets obtained from strain Gage Rosette are categorized by proposed uniformity test. The influence of geometric parameters of the specimen on this test and subsequently on the both uniform and nonuniform calculations is considered.

analysis of influence of strain Gage Rosette on relieved strain
American journal of mechanical engineering, 2013Co-Authors: Patrik Sarga, Peter Senko, František 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.

comparison between grating Rosette and strain Gage Rosette in hole drilling combined systems
Optics and Lasers in Engineering, 2009Co-Authors: Jubing Chen, Yongsheng Peng, Shexu ZhaoAbstract:Hole-drilling method is a most common technique for measuring residual stresses in various materials and structures, in which the strain Gage Rosette is usually used to obtain the strain distributions caused by deformation. To avoid disadvantages in the strain Gage system, different strain measure methods have been proposed in the previous references. In this paper, an optical technique called as grating Rosette and Moire interferometry is presented and compared with the strain Gage one. It is found that higher measure accuracy can be achieved as the hole drilling is combined with the new optical technique instead of the strain Gage Rosette.
