Abstract

General expressions of the crack-tip fields for a dynamically extending crack through an anisotropic elastic material are given. Based on the crack-tip fields, the associated dynamic energy release rate is also derived. Explicit results are given for transversely isotropic materials.

Résumé

On fournit des expressions générales des champs régnant à l'extrémité d'une fissure en expansion dynamique dans un matériau élastique anisotrope. En se basant sur ces champs, on déduit également la vitesse de relaxation de l'énergie dynamique qui y est associée. Des résultats explicites sont fournis pour des matériaux à isotropie transversale.
