Cohesive phase-field fracture with an explicit strength surface: an eigenstrain-based return-mapping formulation
Tim Hageman
Standard phase-field fracture methods are rooted in brittle fracture theory and therefore do not inherently prescribe a material strength for crack nucleation, while also strugglin…

Modeling ice cliff stability using a new Mohr-Coulomb-based phase field fracture model
T. Clayton, R. Duddu, T. Hageman +1
Iceberg calving at glacier termini results in mass loss from ice sheets, but the associated fracture mechanics is often poorly represented using simplistic (empirical or elementary…

Ice viscosity governs hydraulic fracture that causes rapid drainage of supraglacial lakes
Tim Hageman, Jessica MejÃa, Ravindra Duddu +1
Full thickness crevasses can transport water from the glacier surface to the bedrock where high water pressures can open kilometre-long cracks along the basal interface, which can…
