Plasticity and Variable Heredity,

Abstract

The operational definition of variable heredity is compared with that of rate-dependence and they are shown to be unrelated indicative that 'fading memory' and 'plasticity' do not necessarily exclude each other. The problems of characterizing materials with 'plasticity' effects are discussed. Finally, the operational definition for 'plasticity' obtained herein is applied as a necessary condition to various constitutive equations previously proposed for 'plasticity'. Some of these are shown to be unsuited for 'plasticity.' Owing to the special nature of the 'plasticity' a functional constitutive equation showing history dependence in a mathematical sense may fail to reproduce 'plasticity'.
