Abstract
The solution for an angular dislocation allows one to construct the fields for any polygonal loop by superposition. The paper presents the displacements induced by the angular dislocation in an elastic half space. In view of potential applications in geophysics, particular attention is paid to the elastic fields at the free surface. The surface data are seen to exhibit a very simple dependence on the elastic constants.
Résumé
On peut construire les champs élastiques associés à une dislocation en polygone par superposition de solutions au problème d'une dislocation angulaire. Nous présentons les déplacements induits par une dislocation ingulaire dans un demi-éspace élastique. En vue des applications géophysiques, les champs élastiques sur la surface libre sont étudiés en particulier. Nous montrons que les champs élastiques sur la surface dépendent des constantes élastiques d'une facon très simple.
