AbstractThe ratio of lateral strain to axial strain in a non-linear viscoelastic material such as ice depends on fabric, texture, grain size, temperature, load and loading rate, strain and strain rate. Relative contributions of elastic, delayed elastic, and viscous strain to the total strain determine its numerical value. A micromechanically based rheological model has been used to show that material response, however complex, is reasonably predictable and agrees with available experimental results.
