Abstract
In this paper a finite contact problem for two perfectly bonded dissimilar infinite strips is formulated in terms of singular integral equations. Both of the strips are assumed to be isotropic and uniaxial tension is applied to the lower strip away from the contact region. The contact stresses, stress intensity factors and stress distributions in the strips are obtained for various geometries and material combinations. It is also shown that the contact stresses become infinite at the contact ends with a typical square-root singularity.
Résumé
On exprime un problème de contact fini de deux bandes infinies différentes et parfaitement assemblées sur une longueur finie sous la forme d'intégrales singulières. On Suppose que chacune des bandes est isotrope, et qu'une tension uniaxiale est appliquée à la bande inférieure, à une distance suffisante de la zone de contact. On obtient pour diverses géométries et combinaisons de matériaux les contraintes de contact, les facteurs d'intensité de contraintes et les distributions des contraintes dans les bandes. On montre également que les contraintes de contact deviennent infinies aux extrémités de la zone de contact, et présentent une singularité typiquement exprimée par la racine carrée de leur valeur.
