Residual-stress measurement in SS304 seamless tube

Experimental and numerical investigation of residual stress distribution in Al-6061 tubes under using tubular channel angular pressing process by new trapezoidal channel

“…In this method, it is possible to attach the axial and hoop strain gauges both on the external tube surface 24 and on the internal of that. 7,25 Figure 2 Indicates a cylinder with strain gauges mounted on its external surface.…”

Destructive techniques in the measurement of residual stresses in composite materials: an overview

“…An alternative way of using this method is to remove material from the outer surface of tubes. In this case, the strain gages are placed on the inner surface of the tube (Kovač et al ., 1989;Stacey and Webster, 1988). Despite the fact that these techniques can be used for measuring the residual stresses in laminated composite tubes, the Sachs method cannot be used to fi nd the micro-scale residual stresses in a uni-directional GFRP laminate, since the technique cannot differentiate between fi ber and matrix stresses (Reid, 2009).…”

“…The Sachs method technique allows axial, circumferential and radial residual stresses to be determined (Chen et al ., 2000;Garcia-Granada et al ., 2001;Sachs, 1927;Sharman et al ., 1997). It has been used to measure residual stress distribution in metal and ceramic components (Hung, 1989;Jones and Martin, 1977;Kovač et al ., 1989;Kuboki et al ., 2000;Lacarac et al ., 2004;Olson and Bert, 1966;Özdemir and Edwards, 1996;Rasty et al ., 2007;Smith et al ., 1998;Stacey and Webster, 1988;Voyiadjis and Hartley, 1987;Voyiadjis et al ., 1985;Waki et al ., 2003;Yamada et al ., 1990). However, the technique does seem to have been used for composite materials.…”
