Creep Constitutive Equations for Polycrystalline Ice and Effect of Microcracking
The deformation modes of polycrystalline ice are reviewed. Whereas single crystals of ice deform easily by shear on the basal plane, the minimum creep rate of polycrystalline ice is largely controlled by proce...

The Tensile and Compressive Fracture of Ice
The brittle fracture of ice under uniaxial tension and compression is discussed in terms of the nucleation and the propagation of internal cracks. The discussion reveals that fracture under both applied stress...

Structure Geometry and Ice Interaction
The presence of ice usually requires that structures be of different geometry than those in ice free areas. In fact structural form is usually chosen to minimize ice loads. However the engineer often has to ba...
