Abstract : The paper is concerned with the development of the field equations and constitutive equations for small motions superposed on large static deformation of a liquid-filled porous elastic solid, using a basic theory of interacting continua. Two examples of parallel flow in a medium which initially is subjected to a homogeneous deformation is discussed. Also a representation for the solutions of the equations of the infinitesimal theory (analogous to the Boussinesq-Papkovitch representation) is deduced for a class of steady flow. (Author)
