かまぼこのレオロジー的物性と構造に関する研究-V.

Abstract

Both tensile relaxation and shear relaxation in kamaboko were examined. The results obtained were as follows: 1) By a general definition of tensile relaxation modulus, E(t)=ƒ(t)/α-1, the behavior is linear in very narrow extension ratio range, 1.0<α≤1.1. 2) By a definition derived from the equation of state for ideal rubber, E(t)=3•ƒ(t)/α-α-2, the behavior is linear in the whole measured extension ratio range, 1.0<α≤2.0. 3) The behavior in shear is linear in the whole measured strain range, and the relation between tensile relaxation modulus and shear relaxation modulus is given by the equation, E(t)=3•G(t). 4) The generalized Maxwell model or the Eyring-Tobolsky's viscoelasticity theory should be applied to the stress relaxation behavior of kamaboko.
