On the action of Boussinesq forces at a precompressed elastic interface A.P.S. Selvadurai Department of Civil Engineering and Applied Mechanics McGill University Montreal, Canada Abstract This paper examines the axisymmetric elastostatic problem of the separation at a precompressed smooth elastic interface, induced by the action of a doublet of Boussinesq-type concentrated forces. The analysis of the problem focuses on the determination of the zone of separation. The moving boundary nature of the problem stems from the fact that the extent of separation is governed by the magnitudes of the concentrated forces, the precompression and the elasticity characteristics of the system. 1 Introduction The class of elastostatic problems that deal with the contact between smoothly compressed elastic bodies of differing elastic properties has applications to a number of areas of engineering including the study of separation at geomaterial interfaces, the stud
