How Residual Stresses are Measured: An Overview

Abstract Residual stress is generally defined as the stress that is retained in equilibrium in a body or material after manufacturing or processing operations or component usage in the absence of any external forces. This article provides an overview of residual stress measurement methods, including diffraction-based, piezo-spectroscopic/Raman, mechanical, ultrasound, and magnetic techniques. It includes a discussion of measurement planning and execution considerations.
