Résumé

On the basis of photoelasticity method the experimental study of near crack tip stressed strain state in specimens under mixed loading conditions is performed. Carried out experimental investigation allows to obtain coefficients of full asymptotic expansions of stress and displacement fields in the vicinity of the crack tip and alos to find coefficients of highest approach in Williams full asymptotic expansion.

Détail

Keywords: photoelsticity method, mixed loading, digital image processing, highest approaches in asymptotic expansions in the vicinity of the crack tip or angle notch.
