Measuring Multiple Residual Stress Components using Multiple Cuts with the Contour Method - (PPT)

摘要

A = B + C: Variation on Bueckner's superposition principle; Assumes elastic relaxation; Stresses in B unknown except on free boundaries; C by itself give original residual stress on cut plane; Only displace in y-direction since we don't know χ disps. Only gives normal stress (σ_χ in this Fig.).
