Residual stress measurements

RISE have expertise in residual stress measurements and analysis of metallic materials. For more than 20 years, we have done assignments for the Swedish automotive and aerospace industry using XRD and hole drilling.

Cause

RISE measure and analyze residual stresses and how they are altered by various production processes with the purpose to improve, verify or increase knowledge on how process parameters affects residual stresses. This is done by measuring residual stresses of components and test pieces using XRD- or hole drilling techniques.

Residual stresses develops and alters throughout the whole component manufacturing route, that is during casting, rolling, forging, heat treatment and machining. Residual stresses will impact the fatigue life of metallic components, these may be favorable (compressive) or unfavorable (tensile). 

Method

X-ray diffraction (XRD): We are accredited for XRD measurements in accordance with SS-EN-15305:2008 "Non-destructive Testing - Test Method for Residual Stress analysis by X-ray Diffraction". We dispose a number of XRD-systems, which are portable and allows for field measurements.

Hole drilling: We measure residual stresses in accordance with ASTM standard E 837 ”Standard Test Method for Determining Residual Stresses by the Hole-Drilling Strain-Gage Method”.

We can measure components such as; rolls, shafts, plates and castings as  well as additive manufactured components.
