Residual Stress Testing

Added on April 4th 2018

Residual stresses are those which are locked into a component, independent of any external, or applied loads. Residual tensile stresses, often introduced during machining or as a result of uneven cooling of welds or castings are detrimental as they facilitate crack propagation. Shot peening adds a layer of residual compressive stress beneath the surface of a component, which can counter-act tensile residual stresses, and applied (in service) stre... Read more
