Abstract
Horizontally unstretchable continuum of the Westergaard's type is modelled by elastic layers of finite thicknesses interconnected with very thin, flexible but unstretchable sheets. For the regular layered structure, the finite difference equations are formulated and their closed solutions is presented. The resulting formulase are used when the contact problem solution is sought in a form of series of spherical functions. The unknown series coefficients are determined via Galerkine method, the formulae for punch settlement and inclination are presented and a numerical procedure is developed and used to study the influence of the Westergaard's subgrade material parameters ɛ (subgrade reinforcement intensity) and ν (Poisson's ratio of the basic material).
