Fractal frontiers of bursts and cracks in a fiber bundle model of creep rupture
Zsuzsa Danku, Ferenc Kun, Hans J. Herrmann
We investigate the geometrical structure of breaking bursts generated during the creep rupture of heterogeneous materials. Based on a fiber bundle model with localized load sharing…
Poiseuille flow in curved spaces
J. -D. Debus, M. Mendoza, S. Succi +1
We investigate Poiseuille channel flow through intrinsically curved media, equipped with localized metric perturbations. To this end, we study the flux of a fluid driven through th…
Explosive Percolation: Novel critical and supercritical phenomena
Raissa M. D'Souza, Jan Nagler
Explosive Percolation describes the abrupt onset of large-scale connectivity that results from a simple random process designed to delay the onset of the transition on an underlyin…
A lattice Boltzmann method based on generalized polynomials and its application for electrons in metals
Rodrigo C. V. Coelho, Anderson Ilha, Mauro M. Doria
A lattice Boltzmann method is proposed based on the expansion of the equilibrium distribution function in powers of a new set of generalized orthonormal polynomials which are here…
The role of water in the behavior of wood
Dominique Derome, Ahmad Rafsanjani, Stefan Hering +7
Wood, due to its biological origin, has the capacity to interact with water. Sorption/desorption of moisture is accompanied with swelling/shrinkage and softening/hardening of its s…
Multiscale Modeling of Polymer Gels-Chemo-Electric Model versus Discrete Element Model
Thomas Wallmersperger, Falk K. Wittel, Michele D'Ottavio +1
Polyelectrolyte gels are a very attractive class of actuation materials with remarkable electronic and mechanical properties with a great similarity to biological contractile tissu…
Short-lived lattice quasiparticles for strongly interacting fluids
M. Mendoza, S. Succi
It is shown that lattice kinetic theory based on short-lived quasiparticles proves very effective in simulating the complex dynamics of strongly interacting fluids (SIF). In partic…
Progressive Collapse Mechanisms of Brittle and Ductile Framed Structures
Enrico Masoero, Falk K. Wittel, Hans J. Herrmann +1
In this paper, we study the progressive collapse of 3D framed structures made of reinforced concrete after the sudden loss of a column. The structures are represented by elasto-pla…
Hierarchical structures for a robustness-oriented capacity design
Enrico Masoero, Falk K. Wittel, Hans J. Herrmann +1
In this paper, we study the response of 2D framed structures made of rectangular cells, to the sudden removal of columns. We employ a simulation algorithm based on the Discrete Ele…
Coupled DEM-LBM method for the free-surface simulation of heterogeneous suspensions
A. Leonardi, F. K. Wittel, M. Mendoza +1
The complexity of the interactions between the constituent granular and liquid phases of a suspension requires an adequate treatment of the constituents themselves. A promising way…
Lattice-Boltzmann Method for Geophysical Plastic Flows
Alessandro Leonardi, Falk K. Wittel, Miller Mendoza +1
We explore possible applications of the Lattice-Boltzmann Method for the simulation of geophysical flows. This fluid solver, while successful in other fields, is still rarely used…
Lattice Boltzmann model for resistive relativistic magnetohydrodynamics
F. Mohseni, M. Mendoza, S. Succi +1
In this paper, we develop a lattice Boltzmann model for relativistic magnetohydrodynamics (MHD). Even though the model is derived for resistive MHD, it is shown that it is numerica…
Orthotropic rotation-free thin shell elements
Gautam Munglani, Roman Vetter, Falk K. Wittel +1
A method to simulate orthotropic behaviour in thin shell finite elements is proposed. The approach is based on the transformation of shape function derivatives, resulting in a new…
En route to a multi-model scheme for clinker comminution with chemical grinding aids
R. K. Mishra, D. Geissbuhler, H. A. Carmona +7
We present a multi-model simulation approach, targeted at understanding the behavior of comminution and the effect of grinding aids (GAs) in industrial cement mills. On the atomist…
A modeling approach to study the effect of cell polarization on keratinocyte migration
Matthias Jörg Fuhr, Michael Meyer, Eric Fehr +3
The skin forms an efficient barrier against the environment, and rapid cutaneous wound healing after injury is therefore essential. Healing of the uppermost layer of the skin, the…
Cooling Effect of the Richtmyer-Meshkov Instability
F. Mohseni, M. Mendoza, S. Succi +1
We provide numerical evidence that the Richtmyer-Meshkov (RM) instability contributes to the cooling of a relativistic fluid. Due to the presence of jet particles traveling through…
Lattice Boltzmann Model for Electronic Structure Simulations
M. Mendoza, H. J. Herrmann, S. Succi
Recently, a new connection between density functional theory and kinetic theory has been proposed. In particular, it was shown that the Kohn-Sham (KS) equations can be reformulated…
Lattice Boltzmann simulations of a two-dimensional Fermi gas at unitarity
Jasmine Brewer, Miller Mendoza, Ryan E. Young +1
We present fully nonlinear dissipative fluid dynamics simulations of a trapped two-dimensional Fermi gas at unitarity using a Lattice Boltzmann algorithm. We are able to simulate n…
Semi-Spectral Method for the Wigner equation
Oliver Furtmaier, Sauro Succi, Miller Mendoza
We propose a numerical method to solve the Wigner equation in quantum systems of spinless, non-relativistic particles. The method uses a spectral decomposition into $L^2(\mathbb{R}…
Lattice Boltzmann Model for Numerical Relativity
E. Ilseven, M. Mendoza
In the Bona-Masso formulation, Einstein equations are written as a set of flux conservative first order hyperbolic equations that resemble fluid dynamics equations. Based on this f…
Discrete Element Method simulations of the saturation of aeolian sand transport
Thomas Pähtz, Amir Omeradžić, Marcus V. Carneiro +2
The saturation length of aeolian sand transport (), characterizing the distance needed by wind-blown sand to adapt to changes in the wind shear, is essential for accurate mode…
