[Analysis Case] Measurement of Residual Stress in Metal Materials Before and After Load Application Using XRD
It is possible to quantitatively measure tensile and compressive stress non-destructively.
Residual stress measurement is one of the important methods to investigate whether a component can withstand various stress conditions. In XRD (X-ray diffraction), it is possible to determine residual stress by measuring the lattice spacing. This document introduces a case where a sample of aluminum plates with V-shaped processing on both sides was created for tensile testing, and a comparison of residual stress before and after applying tensile load using a tensile testing device, as well as the distribution of residual stress in the sample after application, was confirmed. The residual stress values were determined using the sin²ψ method. For more details, please download the document or contact us.
