Non-destructive testing (NDT) enables users to assess material condition, process quality, and component performance without damaging the part under inspection.

ESPI hole-drilling is a semi-destructive testing method that measures residual stresses by introducing a small drilled hole and using electronic speckle pattern interferometry (ESPI) to capture the resulting surface deformation.

This section presents application notes, technical articles, and research highlights that demonstrate how Stresstech measurement technologies are used in practice.
