Abstract : BY MEASURING THE SHEAR COMPLIANCE OF POLYSTYRENE BY A BALL INDENTATION METHOD AS A FUNCTION OF TIME AT SEVERAL TEMPERATURES, MASTER CURVES IN SHEAR COMPLIANCE AND RELAXATION WERE CONSTRUCTED AT 100 C. THE MASTER CURVE IN RELAXATION WAS COMPARED WITH THAT OBTAINED BY OTHER WORKERS USING A COMBINATION OF TORSIONAL CREEP AND RELAXATION. (AUTHOR-PL).
