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…
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…
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…
