EFFECTS OF MEAN PRESSURE ON THE BEHAVIOR OF A FILLED ELASTOMER

THE RHEOLOGICAL BEHAVIOR OF AN ELASTOMER COMPOSED OF A POLYURETHANE RUBBER FILLED WITH GRANULAR POTASSIUM CHLORIDE IS STUDIED ON THE BASIS OF A SERIES OF COMPRESSION TESTS WITH SUPERIMPOSED HYDROSTATIC PRESSURE. IT IS SUGGESTED THAT BEHAVIOR MAY BE APPROXIMATED BY A LINEAR ANELASTIC RESPONSE FOR RELATIVELY SMALL STRAINS UNTIL A MARKED CHANGE IN STRUCTURE OCCURS, AND THAT FURTHER DEFORMATION INVOLVES SHEAR-DEPENDENT DILATION WHICH IS STRONGLY INFLUENCED BY MEAN PRESSURE. THEORIES ARE SUGGESTED WHICH DESCRIBE THE EXPERIMENTALLY OBSERVED BEHAVIOR.
