BackgroundThere are various experimental measurement techniques used to measure residual stress and this work describes one such method, the slotting its application near surface stresses.ObjectiveThis examines macro-scale specimens.MethodsA series of numerical experiments were performed understand size required assume that specimen is infinitely large, namely thickness, width, height. To asses...

Residual stress is that which remains in a body that is stationary and at equilibrium with its surroundings. It can be very detrimental to the performance of a material or the life of a component. Alternatively, beneficial residual stresses can be introduced deliberately. Residual stresses are more difficult to predict than the in-service stresses on which they superimpose. For this reason, it ...

Most manufacturing processes result in residual stress. The level of residual stress can be high and could affect the structural integrity of the component. Without knowledge of the residual stress field, assessments are often overly conservative. There are many techniques available for residual stress measurement. Mechanical methods, such as centre-hole drilling, have been extensively used but...

This paper reveals the interaction between hydrogen and surface stress in austenitic stainless steel by X-ray diffraction stress measurement and thermal desorption analysis before and after being charged with hydrogen. The surface residual stress was varied by surface finishing using several disc polishing agents. The obtained results show that the residual stress near surface had a significant...
