The static behaviour of a medium consisting of infinite horizontal
layers can be described by an equivalent homogeneous
medium (Schoenberg and Muir, 1989). In this article we give a simplified
notation for the calculation of the equivalent medium and discuss the
question of how an equivalent medium should be defined.
If stress is applied on the top boundary of a stack of layers and the
homogeneous equivalent medium, both media
show identical changes in elastic deformation energy within the medium and
the same exterior displacements and average forces on the boundaries.
