โฆ Synopsis
This paper examines the composite, two-dimensional, linear elastic wedge for singular stresses at its vertex. A full range of wedge boundary and matching conditions is considered. Using separation of variables on the Airy stress function, the usual determinant conditions for singularities of the form O(r -x) as r --~ 0 are established and further conditions are derived for singularities of the form O(r -x In r) as r ~ 0.
The order of the determinant involved in these conditions depends upon the number of materials comprising the wedge. Two systematic methods of expanding the determinant for the N-material wedge are presented.
RESUME
Ce papier examine le coin compos~, lin~aire et 61astique, en deux dimensions, pour d6terminer les contraintes singuli~res ~ son sommet. On va consid6rer la rang6e totale des conditions aux limites du coin, et les conditions correspondantes dans le coin. On se sert de la s6paration des variables de la fonction de contrainte d'Airy, pour d6terminer les conditions usuelles sur le d~terminant pour les singularit6s de la forme O(r -x) quand r ~ 0, et on d~rive des conditions additionnelles pour les singularit6s de la forme O(r -x In r) quand r--~ 0. L'ordre du d6terminant impliqu~ dans ces conditions d6pend du nombre des mat6riaux dans le coin. D'abord on propose deux m6thodes syst6matiques de d~velopper le d6terminant du coin de N-mat~riaux.

The nature of the stress field occurring at the vertex of an angular elastic plate under in-plane loading is reconsidered. An additional boundary condition is introduced. This boundary condition reflects the action of cohesive stress-separation laws. Companion asymptotic analysis proceeds routinely
An elastic plane body, shaped like a circular ring or a disk, is subjected to radial surface forces varying according to a sinusoidal law. The existence of a tensile region included in a purely compressive one is proven and its asymptotic behaviour studied when the surface forces converge to two con
