  • deformable porous solid;
  • fluid, amorphous substance - molecules moving freely past one another;
  • porous solid of solid matrix and pore space - saturated by fluid mixture, fluid–solid mixture;
  • Lagrangian description of deformation of body - motion of its material particles;
  • deformation, inducing changes in length of material vectors and angles formed;
