Abstract
The Reciprocal Work Contour Integral Method of Stern, et al. is extended so that computation can be made of fracture mechanics parameters at the corner formed by arbitrarily oriented stress free surfaces. Two numerical examples are given. In one, results are compared to those obtained using an overdetermined collocation technique.
Résumé
On procède à une extension de la méthode d'étude par intégrale de contour du travail réciproque, proposée par Stern et Al, en vue de calculer les paramètres de mécanique de rupture correspondant à l'angle formé par deux surfaces d'orientation arbitraire et libres de contrainte. Deux exemples numériques sont fournis, avec, pour l'un, une comparaison des résultats avec ceux que fournit une technique de collocation redondante.
