“…Though, destructive & non-destructive type measurement approaches are included in this group but all possible varieties of measurement techniques are not equally effective. Some mostly used destructive stress measurement techniques are a) Sectioning Method 2, 3,9) b) Contour Method 10,11) c) Hole-drilling Method 1,2,3) d) Slitting method 12,13) e) Ring core Method 14,15) etc. Nowadays, several advanced non-destructive techniques like X-ray diffraction (XRD) technique 16,17) , Neutron diffraction technique 18,19) , Ultrasonic technique 20,21) , Positron annihilation spectroscopic technique (PAS) 22) , Barkhausen noise method 23,24) etc.…”

Welding residual stress is considered as one of the most responsible factors by the experts for premature failure of the in-service welded structures. Between tensile residual stress and compressive residual stress, while the former type is found to have detrimental effect on the welded part, compressive stress may adhere to some benefits in many cases. It is, therefore, very important to evaluate the welding residual stress in a welded component properly so that suitable measures can be adopted to get the optimized service life of the fabricated structure. The measurement techniques of welding residual stress have been classified into different categories, significantly in destructive and non-destructive in nature. The hole drilling technique is one of the destructive methodologies to measure the welding residual stress using strain gauges which is standardized by ASTM E-837 and frequently used in the applied field. In this review paper, an effort has been given to understand the fundamentals of the hole drilling method based on extensive literatures' study which reflects the chronological developments of this technique in the field of stress measurement. This paper, further, describes the influence of different operational parameters associated with the hole drilling technique on the outcome of the process.

“…The residual stress at the surface of the coating was determined using the strain reading obtained at a depth of 20 µm. The strain gauge readings were affected by cutting induced stresses and hence cannot be used to evaluate the throughthickness residual stress [44]. The residual stress calculated at a depth of 20 µm is as given below for different coatings.…”

Thermal barrier coating (TBC) with Al 2 O 3 and 8YSZ as topcoat constituents has been developed. The commercially available 8YSZ (80% wt.), Al 2 O 3 (17 and 19% wt.) and multiwall carbon nanotubes (MWCNT) (3% and 1% wt.) were plasma sprayed to produce composite coatings. A stress relaxation technique using a slow-speed diamond cutter has been used to relax the strain and determine the through-thickness residual stress in the coatings. A 3D finite element model was developed, the model was experimentally validated, and the model was used to establish a relationship between applied stress and relaxed strain. The addition of alumina increased the compressive residual stress on the surface of the coating by 42%, the addition of 1% MWCNT had a negligible effect on the residual stress on the coating surface. The further addition of MWCNT (3% wt.) resulted in tensile residual stress in the coating as a result of MWCNT agglomeration.

“…This enables the users to predict the warping of the workpieces during machining, and thus to adjust and adapt the machining sequence accordingly. As a general remark, several methods have been presented in the literature to estimate residual stress distributions, see the survey presented in Cheng and Finnie (2007). All these techniques share the same feature: the residual stress is released, and the resulting change of geometry is measured.…”
