An acoustoelastic technique for the complete evaluation of plane states of residual stress
Abstract
A new acoustoelastic technique for the complete evaluation of plane states of residual stress is presented. This particular technique uses longitudinal waves propagating normal to the plane of stress. The two-dimensional equilibrium equations are differentiated and added, yielding a Poisson's equation for the in-plane shear stress in which the forcing function is obtained from the measured velocity changes. The basic theory is presented along with experimental results for residual stress determination in an aluminum plate.
