    Description / Table of Contents: Résumé On examine l'application du principe de la mécanique linéaire de rupture aux matériaux composites orthotropes. On montre que la ténacité à la rupture de composites unidirectionnels est indépendante de la longueur de la fissure mais dépend de l'orientation des fibres par rapport à cette fissure. Pour vérifier de manière expérimentale les principes ci-dessus, on a utilisé un matériau en verre epoxy unidirectionnel (Scotchply 1002). La ténacité à la rupture du Scotchply 1002 pour différentes orientations fibre/fissure a été obtenue en utilisant un programme à élément fini Solid Sap et des éprouvettes de traction compactes. On a trouvé une formule empirique mettant en relation la ténacité à la rupture du matériau pour différentes orientations fibre/fissure.
    Notes: Abstract Application of the principles of linear fracture mechanics to the orthotropic composite materials is examined. It is shown that fracture toughness of unidirectional composites is independent of crack length but dependent on crack-fiber orientation. For experimental verification of the above principles, uni-directional glass epoxy material (Scotchply 1002) was used. The fracture toughness of Scotchply 1002 for different crack-fiber orientations is obtained by utilizing Solid Sap finite element program and compact tension specimens. An empirical formula relating the fracture toughness of the material for different crack-fiber orientation is found.
