Adaptive Crack-Tip Localization of Phase-Field Fracture Computations
Aarosh Dahal, Aditya Kumar
Phase-field models of fracture provide a unified framework for simulating crack nucleation and propagation, but their computational cost remains high because the governing equilibr…
Adaptive Mesh Coarsening for Efficient Phase-Field Fracture Simulations
Aarosh Dahal, Abhinav Gupta, Aditya Kumar
Phase-field models provide a versatile framework for simulating fracture nucleation and propagation without explicit crack tracking. Their principal computational challenge is the…
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…
On failure mechanisms and load-parallel cracking in confined elastomeric layers
Aarosh Dahal, Aditya Kumar
Thin layers of elastomers bonded to two rigid plates demonstrate unusual failure response. Historically, it has been believed that strongly-bonded layers fail by two distinct mecha…
A comparison of phase field models of brittle fracture incorporating strength: I -- Mixed-mode loading
Umar Khayaz, Aarosh Dahal, Aditya Kumar
The classical variational phase-field model for brittle fracture effectively predicts the growth of large pre-existing cracks. However, the modeling of crack nucleation continues t…
