Record #96656:

A differential flow model for polycrystalline ice / S. Shyam Sunder, Mao S. Wu.

Title: A differential flow model for polycrystalline ice / S. Shyam Sunder, Mao S. Wu.
Author(s): Sunder, S. Shyam.
Wu, Mao S.
Date: 1989.
In: Cold Regions Science and Technology. (1989.), Vol. 16(1) (1989)
Abstract: Theory based on concept of state variables and accounts for two mechanisms of deformation rate: transient and steady-state flow. Dimensional requirements for creep as well as constant deformation-rate stress-strain response are satisfied. Correspondence is established between constant-stress creep and constant strain-rate tests. Uniaxial model contains six parameters and follows experimental data on creep of fresh-water polycrystalline ice obtained by earlier workers.
