Dual-axis Hole-drilling Espi Residual Stress Measurements

چکیده

A dual-axis ESPI hole-drilling residual stress measurement method is described. It has the advantage of evaluating all the in-plane normal stress components with similar response to measurement errors, significantly lower than with single-axis measurements. Experimental tests were done on a stressed specimen, and the results supported theoretical expectations.

Residual Stress Characterization in Orthotropic Plate by Combining Hole-drilling Method and Speckle Interferometry

Novel method for a determination of residual stresses in orthotropic composite plates based on local displacement measurements by electronic speckle-pattern interferometry is developed and verified. The values of hole diameter increments in principal residual stress directions serves as initial experimental deformation. The technique is based on analytical solution of S.G. Lekhnitsky, which des...

Numerical and Experimental Study of Residual Stress Measurement and Thickness Distribution of T-shape Steel Tube Produced by Tube Hydroforming

Tube hydroforming (THF) process is used to produce the complex components from the initial cylindrical tubes. In this paper, T- shape component was formed using a tube hydroforming machine and the residual stresses of hydroformed tube was determined by hole drilling method. Subsequently, the thickness distribution and residual stresses of final tube were investigated using experimental and fini...

Effect of the Hole-bottom Fillet Radius on the Residual Stress Analysis by the Hole Drilling Method

The hole drilling method is based on the measuring of the surface relaxed strains when a small hole is drilled on the examined component. From the relaxed strains, measured generally by using special strain gage rosette, the residual stresses is computed by using proper influence coefficients, provided also by the ASTM E837-08 standard. Such influence coefficients are obtained by numerical simu...

Experimental Study of the Residual Stresses in Girth Weld of Natural Gas Transmission Pipeline

In order to achieve integrated condition in the girth welding of high pressure natural gas transmission pipelines, the weld zones and its surrounding area should have good mechanical properties. Residual stresses are an important defect especially in the girth welding of the pipeline. In this study, two API X70 steel pipes (with spiral seam weld) of 56 inches outside diameter and 0.780 inch wal...
