Thermal Modifications of Welding Residual Stressesin butt welded schedule 80 austenitic stainless steel pipes are usually tensile in the weld heat affected zone. Compressive stresses can be induced instead by heat sink welding, whereby the ID is water cooled after the second welding layer while the rest of the weld is completed. The tensile stresse

Shot Peening and Residual Stresses fatigue behavior is for example a consequence of either the strain hardening of surface layers or of the compressive residual stresses in surface layers induced by shot peening or of both. It depends upon the strength or hardness of the material and upon the geometry of the workpiece which of these

Measurement of Throughwall Residual Stresses in Large-Diameter Piping Butt Weldments Using Strain-Ga butt weldments are presented. One weldment was fabricated using a conventional welding procedure; the other weldment was fabricated by a heat sink welding procedure in which water-spray cooling was applied to the inner surface after the initial closure pass. Throughwall residual stress distribution

The extent of recovery and tempering that occurred during relaxation was displayed by means of isochronous stress vs strain curves constructed from multiple loading tests. Rec

Effect of Temperature on Stress Relaxation of Several Metallic Materialsore sensitive to changes in temperature than to changes in the applied stress. It is shown that heat treatment will minimize stress relaxation by either reducing residual stress or by inducing strengthening mechanisms such as age hardening. In some alloy systems stress relaxation may proceed simulta

Linear Elastic Fracture Mechanics and Fatigue Crack Growth — Residual Stress Effects concepts is logical and consistent. The importance of both geometry and loading in the determination of stress intensity factor (K) is indicated, as is the validity of the superposition technique as applied to cracks in residual stress fields. Methods of determining K are described, with emphasis o
