Systems and methods for rapid force-based measurements of residual stress

Abstract

Systems and methods that directly measures forces caused by residual stresses in components. The components may be manufactured components including via Additive Manufacturing (AM). The system and method may use a small force sensor fitted onto a part of the component and a force sensor may be placed/fitted near a region of expected residual stress of the component. The tension device may be tensioned to apply a small preload onto the component while a relaxation technique is applied to regions of the component while measuring the load on the force sensor. Regions may be individually and sequentially relaxed by slitting the regions via wire electrical discharge machining (EDM) while measuring the load on the force sensor to directly measure force caused by residual stress within the component.
