Abstract
Combining experimental and computational method for determination of the singular and the nonsingular
stress terms along the front of the 3D surface crack is proposed. Evaluation of the terms is based on
comprehensive comparison between deformation responses (for measurement points on the surface) obtained
experimentally and from numerical solutions of the corresponding boundary problem of solid mechanics. The
proposed approach allows carrying out an adequate and a comprehensive assessment of stress fields in the
vicinity of the surface crack front.
