Abstract
An improved method of determining higher order eigenvector coefficients associated with a general opening crack in a similar or bi-material configuration is presented. The method is based on the reciprocal work contour integral method. The method is tested on two problems of known solution. The method is found to be insensitive to finite element idealization error.
Résumé
On présente une méthode améliorée pour déterminer les coéfficients d'eigenvector associés à une fissure ou à une entaille de type général en ouverture, dans une configuration de matériaux similaires ou de bimatériaux. La méthode est basée sur une méthode d'intégrale de contour d'un travail réciproque. On la met à l'épreuve sur deux problèmes dont la solution est connue. On la trouve insensible à une erreur dans l'idéalisation des éléments finis.
