A Coefficient of Viscous Extension

Abstract

WHILE working on a generalized theory on straining of amorphous or quasi-amorphous solids, it became clear that one could include the straining of viscous fluids by means of a suitable stress-strain parameter λ which I call a ‘coefficient of viscous extension' related to the ‘coefficient of viscous shear' usually called1 the coefficient of viscosity µ. In this communication only the flow strain component of a deformed substance2 is considered, so that the elastic and plastic components3 are neglected and, further, only isotropic substances are discussed.
