Abstract : The rheological behavior of an elastomer composed of a polyurethane rubber filled with granular KC1 is analyzed in compression with superimposed hydrostatic pressure as well as under conditions of relaxation of unconfined compression. It is suggested that this behavior may be approximated by a volume-constant linear anelastic response for relatively small strains until a marked change in structure occurs after which further deformation involves dilatation dependent on mean pressure. After large deformation, rapid recovery of shape to very near initial configuration is found to occur upon unloading. Theories are proposed which describe the observed behavior. (Author)
