   Abstract:
   THE CONSTITUTIVE RESPONSE PREDICTED BY THE NEW ENDOCHRONIC THEORY WITH SINGULAR KERNEL FOR NON-PROPORTIONAL LOADING INVOLVING AN ABRUPT CHANGE IN THE LOADING DIRECTION IN STRESS SPACE IS INVESTIGATED ANALYTICALLY. FOR SUCH LOADING, THE RESPONSE IS DETERMINED, AS A FUNCTION OF THE ANGLE BETWEEN THE ORIGINAL AND THE REVISED LOADING DIRECTIONS, FOR INFINITESIMAL LOADING INCREMENTS IN THE REVISED DIRECTION. IT IS SHOWN THAT THE NEW ENDOCHRONIC THEORY DIFFERS IN IMPORTANT AND FUNDAMENTAL WAYS FROM CLASSICAL PLASTICITY WITH HARDENING. FOR INFINITESIMAL DEFORMATIONS, THE TWO THEORIES EXHIBIT SIMILARRESPONSE CHARACTERISTICS ONLY UNDER VERY SPECIALIZED CONDITIONS. FOR FINITE DEFORMATIONS, THE NEW ENDOCHRONIC THEORY LEADS TO PLASTIC FLOW FOR ALL LOADING DIRECTIONS, WHILE THE TYPE OF RESPONSE PREDICTED BY CLASSICAL PLASTICITY THEORY DEPENDS UPON THE DIRECTION OF LOADING.
