摘要

1. Introduction The inherent strain method [1] is a destructive technique to measure the residual stress accurately by cutting up the welding structure to be measured. The residual stress is represented by Eq.1; using inherent strain: where {σ} is residual stress, {ε~*} is inherent strain, [d] is the matrix between elastic stress and strain, and [H~*] is the elastic response matrix between inherent strain and elastic strains.
