A new constitutive equation on ice materials

mechanical behaviour of ice. Gagnon (2011) used a crushable material model and defined two stress curves: yield stress versus volumetric strain. This model was able to solve problems in which the top layer of ice was melting and the lower layers of ice remained solid. Figure 1 illustrates the stress-strain relations as discerned by Gagnon.

A new formula is proposed for the end-bearing capacity of piles penetrating into crushable soils. The formula is based on a breakage mechanics model that accounts for the evolution of the grain size distribution (GSD) due to grain crushing with only physically meaningful parameters. The model is integrated using the finite-element method to ...
