Finite element method–discrete element method bridging coupling for the modeling of gouge
Jean-François Molinari, Guillaume Anciaux, Antonio Joaquin Garcia Suarez, Manon Eugénie Voisin--Leprince
We discuss the multiscale modeling of a granular material trapped between continuum elastic domains. The amorphous granular region, usually termed “gouge,” is under high confinement pressure, to represent the loading of faults at depth. We model the granul ...
2022Exploring the inner workings of the clove hitch knot
Pedro Miguel Nunes Pereira de Almeida Reis, Tomohiko Sano, Paul Johanns, Changyeob Baek, Paul Grandgeorge
We perform a combined experimental and computational investigation of the clove hitch knot. We develop a physical model for the clove hitch by tying an elastic rod onto a rigid cylinder. In the experiments, we characterize the mechanical performance, geome ...
ELSEVIER2022Computational micromechanics of porous brittle solids
Johan Alexandre Philippe Gaume, Henning Löwe, Lars Kristoffer Uhlen Blatny, Stephanie Wang
Porous brittle solids evidence complex mechanical behavior, where localized failure patterns originate from mechanical processes on the microstructural level. In order to investigate the failure mechanics of porous brittle solids, we outline a general stoc ...
2021Multi-physical characterization of cellular ceramics for high-temperature applications
The use of cellular ceramics in enhancing the performance of a high-temperature latent heat thermal energy storage unit was investigated. A detailed design methodology is presented, which consists of a combined analytical-numerical analysis followed by a m ...
EPFL2020Planar hydraulic fracture growth perpendicular to the isotropy plane in a transversely isotropic material
Brice Tanguy Alphonse Lecampion, Haseeb Zia, Fatima-Ezzahra Moukhtari
The configuration of a hydraulic fracture (HF) propagating perpendicular to the isotropy plane of a transversely isotropic (TI) material is encountered in most sedimentary basins. We account for both elastic and fracture toughness anisotropy, and investiga ...
2020Integrating the Finite Element Method with a Data-Driven Approach for Dam Displacement Prediction
Zhenzhu Meng, Yating Hu, Chenfei Shao
Both numerical simulations and data-driven methods have been applied in dam's displacement modeling. For monitored displacement data-driven methods, the physical mechanism and structural correlations were rarely discussed. In order to take the spatial and ...
2020Finite Element Modeling of Tight Elastic Knots
Pedro Miguel Nunes Pereira de Almeida Reis, Tomohiko Sano, Paul Johanns, Changyeob Baek, Paul Grandgeorge
We present a methodology to simulate the mechanics of knots in elastic rods using geometrically nonlinear, full three-dimensional (3D) finite element analysis. We focus on the mechanical behavior of knots in tight configurations, for which the full 3D defo ...
