“…The experimental methods most commonly used to research work on elastic-plastic problems are: photoelasticity, especially the method of photoelastic coating (Pacey et (Lin, 2000;Balalov et al, 2007), electronic speckle pattern interferometry method (ESPI) (Diaz et al, 2001;Schajer et al, 2005), digital image correlation method (DIC) (Vural et al, 2011;Diaz et al, 2004;Tarigopula et al, 2008), strain gauge technique (Rasty et al, 2007;Olmi, 2010), thermography (Pieczyska et al, 2006;Connesson et al, 2011).…”

In the paper, the possibility of application of various experimental methods to the analysis of elastic-plastic states at different levels of material plastifying is presented. For tests carried out on two-dimensional elements with different stress concentrators and loaded by tensile stresses, three experimental methods have been selected: Moiré method, method of photoelastic coating and the thermography method. On the basis of the tests results, the range of the applicability of chosen methods and their suitability to the elastic-plastic strain analysis at the development of material plastifying has been determined. The strain components distribution obtained from the Moiré method and the method of photoelastic coating has been compared. The possibility of increasing the accuracy of strain determination for the Moiré method by additional tests at the grid rotated by an angle of 45• with respect to the direction of tensile stress has been shown. The results of the investigations have been discussed.

“…A modern variant, Electronic Speckle Pattern Interferometry (ESPI) has become popular because its use of a video camera allows "live" fringe patterns to be produced by image subtraction [35][36][37]. Figure 4 shows an example ESPI fringe pattern created by hole-drilling.…”

Since its inception by Mathar in the 1930s, the hole-drilling method has grown to be the most widely used general-purpose technique for measuring residual stresses in materials. During its history, the method has progressed greatly in both sophistication and scope, with substantial advances in all three of its main aspects. Drilling procedures have developed from the early use of a conventional low-speed drill to the modern use of highspeed orbiting endmills and, for very hard materials, abrasive machining. Deformation measurements have advanced from the use of a mechanical extensometer to strain gauges and full-field optical measurements such as Moiré, ESPI and Digital Image Correlation. Computation techniques have progressed from empirical calibrations for discrete measurements within uniform stress fields to finite-element inverse solutions for multiple measurements within non-uniform stress fields. This paper gives an overview of the history and progress of all three aspects of the hole-drilling method, and indicates some promising directions for future developments.

“…This is an attractive alternative approach because it is relatively straightforward to implement and can produce "live" fringe patterns by image subtraction [47][48][49][50]. Stepping the reference beam using a piezoelectric phase shifter enables the local phase to be determined at each measured pixel [36,39,50,51]. This is a very significant feature because it enables the evaluation of phase change throughout the observed area and greatly facilitates residual stress evaluations using full-field data instead of a few fringe values at selected points.…”

“…This is a very significant feature because it enables the evaluation of phase change throughout the observed area and greatly facilitates residual stress evaluations using full-field data instead of a few fringe values at selected points. Figure 4 shows a typical ESPI arrangement [50]. The light from a coherent laser source is divided into two beams, one of which illuminates the specimen surface and is subsequently imaged by a CCD camera, while the second feeds directly to the CCD camera where it creates an interference pattern on the CCD surface.…”

Residual stress measurements by hole-drilling have developed greatly in both sophistication and scope since the pioneering work of Mathar in the 1930s. Advances have been made in measurement technology to give measured data superior in both quality and quantity, and in analytical capability to give detailed residual stress results from those data. On the technology side, the use of multiple strain gauges, Moiré, Holographic Interferometry and Digital Image Correlation all provide prolific sources of high quality data. In addition, modern analytical techniques using inverse methods provide effective ways of extracting reliable residual stress results from the mass of available data. This paper describes recent advances in both the measurement and analytical areas, and indicates some promising directions for future developments.
