Williams expansion-based approximation of the stress field in an Al 2024 body with a crack from optical measurements	2017	9	.pdf	application/pdf	4759	270	55	S. Seitl et alii, Frattura ed Integrità Strutturale, 41 (2017) 323-331; DOI: 10.3221/IGF-ESIS.41.43 324 INTRODUCTION haracterization of crack tip stresses has been an area of active research for many decades; see short state-of-art in [1, 2] presenting an over-deterministic least squares technique to evaluate the mixed-mode multi-parameter stress field by photo- elasticity underlining the fact that the use of a multi-parametric representation is not just for academic curiosity but a necessity in some cases of engineering interest.
