Dynamic phase-field model for brittle fracture in grounded glaciers
Aarosh Dahal, Umar Khayaz, Ravindra Duddu +1
Fracture and calving of glaciers are key contributors to ice-mass loss and sea-level rise, yet predictive modeling remains challenging. Fracture in grounded glaciers is driven by g…
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 Mejía, 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…
Physics informed cell representations for variational formulation of multiscale problems
Yuxiang Gao, Soheil Kolouri, Ravindra Duddu
With the rapid advancement of graphical processing units, Physics-Informed Neural Networks (PINNs) are emerging as a promising tool for solving partial differential equations (PDEs…
A stress-based poro-damage phase field model for hydrofracturing of creeping glaciers and ice shelves
T. Clayton, R. Duddu, M. Siegert +1
There is a need for computational models capable of predicting meltwater-assisted crevasse growth in glacial ice. Mass loss from glaciers and ice sheets is the largest contributor…
A stabilized finite element method for delamination analysis of composites using cohesive elements
Gourab Ghosh, Ravindra Duddu, Chandrasekhar Annavarapu
We demonstrate the ability of a stabilized finite element method, inspired by the weighted Nitsche approach, to alleviate spurious traction oscillations at interlaminar interfaces…
Numerical Investigation of Critical Electrochemical Factors for Localized Corrosion using a Multi-species Reactive Transport Model
Xiangming Sun, Jayendran Srinivasan, Robert G. Kelly +1
A multi-species reactive transport model based on the sequential non-iterative approach is employed to investigate two major stages involved in artificial pit experiments of stainl…
