Dynamic phase-field model for brittle fracture in grounded glaciers
Aarosh Dahal, Umar Khayaz, Ravindra Duddu +1
The paper presents a dynamic phase‑field model for brittle fracture in grounded glaciers, showing that incorporating inertia yields realistic, sharp crevasse propagation unlike qua…
Why planar cracks fragment into echelon cracks
Olivia Ward, Aditya Kumar
Predicting the path and shape of growing cracks is fundamental to understanding of fracture. Under out-of-plane shear loading, an initially planar crack may spontaneously fragment…
Rational Mechanics of Material Strength in Brittle Solids
Arash Yavari, Aditya Kumar
Material strength is a classical concept with renewed importance in fracture mechanics, particularly in crack nucleation in brittle solids. We formulate material strength in finite…
The phase-field model of fracture incorporating Mohr-Coulomb, Mogi-Coulomb, and Hoek-Brown strength surfaces
S Chockalingam, Adrian Buganza Tepole, Aditya Kumar
Classical phase-field theories of brittle fracture capture toughness-controlled crack growth but do not account for the material's strength surface, which governs fracture nucleati…
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…
Emergence of tension-compression asymmetry from a complete phase-field approach to brittle fracture
Chang Liu, Aditya Kumar
The classical variational approach to brittle fracture propagation does not distinguish between strain energy accumulation in tension versus compression and consequently results in…
