Computation of stresses in jammed packings modeled with Tresca friction
Frédéric Marazzato, Shankar Venkataramani
This paper is interested in the computation of stresses within jammed packings of rigid polygonal cells. The cells are considered to follow a Tresca friction law. First, a constrai…

Discrete Differential Geometry for Hyperbolic Surfaces of Non-Constant Curvature
Christian Parkinson, Shankar C. Venkataramani
We develop a discrete differential geometry for surfaces of non-constant negative curvature, which can be used to model various phenomena from the growth of flower petals to marine…

Coupled KPZ equations and their decoupleability
Boliang Fu, Tadahisa Funaki, Sunder Sethuraman +1
We discuss characterizations of the decoupleability, partial and full, of trilinear or completely symmetric real tensors, which inform on the structure of certa…
