Sur le contact adhésif entre un poinçon axisymétrique rigide et un milieu élastique semi-infini

A particular superposition of coaxial cylinders is used to describe the adhesive contact between an axi-symmetric punch and an elastic material. The proposed formalism allows us to simply find the equations of the adhesive contact when the range of the interfacial forces is supposed to be zero (Maugis and Barquins ' generalisation of Johnson et al. 's results) and when the interfacial force law is described using the Dugdale model. In the latter case, explicit expressions are given for an arbitrary axi-symmetric punch profile.
