Abstract
The situation where a screw dislocation pile up (or a crack in anti plane strain) crosses a bimaterial interface is considered. It is shown that a closed form solution can be obtained when the pile up crosses the interface in a symmetric fashion.
Resume
On discute le problème d'un empilement de dislocations-vis (ou d'une fissure sous déformation anti-plan) qui traverse l'interface entre deux matériaux aux propriétés différentes. On démontre l'existence d'une solution explicite dans le cas où l'empilement traverse l'interface de façon symétrique.
