Abstract
The paper deals with the problem of finding the distribution of stress in the neighbourhood of a Griffith crack located at the interface of two bonded dissimilar elastic half-spaces. The crack is excited by a normally incident antiplane shear wave. The problem is reduced to that of solving a Fredholm integral equation. Both the iterative and numerical solutions have been obtained. The solutions are used for calculating numerical values of quantities of physical interest such as dynamic stress intensity factor and the amplitude of distance between the edges of the crack.
Résumé
Le mémoire est relatif au problème qui consiste à trouver la distribution des contraintes au voisinage d'une fissure de Griffith située à l'interface de deux demi-espaces élastiques dissemblables et collés. La fissure est mise en mouvement par une onde de cisaillement antiplanaire avec une incidence normale. Le problème est ramené à celui de trouver une équation intégrale de Fredholm. On a obtenu à la fois des solutions itératives et numériques. Ces solutions sont utilisées pour calculer les valeurs numériques de certaines quantités d'intérêt physique, telles que le facteur d'intensité des contraintes dynamiques, et l'étendue de la distance entre les extrémités d'une fissure.
