Viscoelastic Functions for Soil1

  1. Lawrence J. Waldron2

Abstract

Abstract

Briquets of Yolo silt loam have previously been shown to be viscoelastic. Three viscoelastic functions which describe the stress, strain, and time relations for two types of loading were obtained when the soil was in equilibrium with humidities ranging from 15 to 90% at 70°F. These functions were the shear creep compliance, the distribution of retardation times, and the complex shear compliance. The functions were very sensitive to small changes in water content. Equal-time shear creep compliances were exponential functions of water content. Increasing temperature from 40° to 100°F apparently did not change the rates of the deformation process uniformly since temperature coefficients of equal-time compliances reversed sign as the stress duration passed from 1 to 7,200 seconds. The functions are discussed in terms of a two-phase concept.
