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…
Nonlinear Mechanics of Arterial Growth
Aditya Kumar, Arash Yavari
In this paper, we formulate a geometric theory of the mechanics of arterial growth. An artery is modeled as a finite-length thick shell that is made of an incompressible nonlinear…
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…
