Predicting cement microstructure and mechanical properties in hydrating cement paste with a Phase-Field model
Alexandre Sac-Morane, Katerina Ioannidou, Manolis Veveakis +1
Predicting the evolving microstructure of hydrating cement is essential for understanding and modeling its mechanical property development. Physics-based continuum approaches offer…
Influence of the dividing surface notion on the formulation of Tolman's law
Martin Thomas Horsch
The influence of the surface curvature on the surface tension of small droplets at equilibrium with a surrounding vapour, or small bubbles at equilibrium with a surrounding liquid,…
Loss of memory of an elastic line on its way to limit cycles
Elisabeth Agoritsas, Jonathan Barés
Under an oscillating mechanical drive, an amorphous material progressively forgets its initial configuration and might eventually converge to a limit cycle. Beyond quasistatic driv…
Ion specificity of confined ion-water structuring and nanoscale surface forces in clays
Francis Dragulet, Abhay Goyal, Katerina Ioannidou +2
Ion specificity and related Hofmeister effects, ubiquitous in aqueous systems, can have spectacular consequences in hydrated clays, where ion-specific nanoscale surface forces can…
Experimental validation of a micromechanically-based compaction law for soft/hard grain mixtures
Manuel Cárdenas-Barrantes, Jonathan Barés, Mathieu Renouf +1
In this letter, we report on an experimental study which analyzes the compressive behavior of 2D bidisperse granular assemblies made of soft (hyperelastic) and hard grains in varyi…
The physics of cement cohesion
Abhay Goyal, Ivan Palaia, Katerina Ioannidou +5
Cement is one of the most produced materials in the world. A major player in greenhouse gas emissions, it is the main binding agent in concrete, to which it provides a cohesive str…
Strength and energy consumption of inherently anisotropic rocks at failure
David Cantor, Carlos Ovalle, Emilien Azéma
Using a discrete-element approach and a bonding interaction law, we model and test crushable inherently anisotropic structures reminiscent of the layering found in sedimentary and…
Bulk modulus of soft particle assemblies under compression
David Cantor, Manuel Cárdenas-Barrantes, Itthichai Preechawuttipong +2
Using a numerical approach based on the coupling of the discrete and finite element methods, we explore the variation of the bulk modulus K of soft particle assemblies undergoing i…
Highly strained mixtures of bidimensional soft and rigid grains: an experimental approach from the local scale
Jonathan Barés, Manuel Cárdenas-Barrantes, David Cantor +2
Granular systems are not always homogeneous and can be composed of grains with very different mechanical properties. To improve our understanding of the behavior of real granular s…
Micromechanical description of the compaction of soft pentagon assemblies
Manuel Cárdenas-Barrantes, David Cantor, Jonathan Barés +2
We analyze the isotropic compaction of assemblies composed of soft pentagons interacting through classical Coulomb friction via numerical simulations. The effect of the initial par…
Controlling crackling dynamics by triggering low intensity avalanches
Jonathan Barés, Daniel Bonamy
We examine the effect of small, spatially localized, excitations applied periodically in different manners, on the crackling dynamics of a brittle crack driven slowly in a heteroge…
Compaction of mixtures of rigid and highly deformable particles: a micro-mechanical model
Manuel Cárdenas-Barrantes, David Cantor, Jonathan Barés +2
We analyze the isotropic compaction of mixtures composed of rigid and deformable incompressible particles by the non-smooth contact dynamics approach (NSCD). The deformable bodies…
Effects of particle compressibility on structural and mechanical properties of compressed soft granular materials
Thi-Lo Vu, Saeid Nezamabadi, Serge Mora
Changes in the mechanical properties of granular materials, induced by variations in the intrinsic compressibility of the particles, are investigated by means of numerical simulati…
Cutting and slicing weak solids
Serge Mora, Yves Pomeau
Dicing soft solids with a sharp knife is quicker and smoother if the blade is sliding rapidly parallel to its edge in addition to the normal squeezing motion. We explain this commo…
Yielding, Rigidity, and Tensile Stress in Sheared Columns of Hexapod Granules
Yuchen Zhao, Jonathan Barés, Joshua E. S. Socolar
Granular packings of non-convex or elongated particles can form free-standing structures like walls or arches. For some particle shapes, such as staples, the rigidity arises from i…
Transparent Experiments: Releasing Data from Mechanical Tests on Three Dimensional Hydrogel Sphere Packings
Jonathan Barés, Nicolas Brodu, Hu Zheng +1
We describe here experiments on the mechanics of hydrogel particle packings from the Behringer lab, performed between 2012 and 2015. These experiments quantify the evolution of all…
Sheared Amorphous Packings Display Two Separate Particle Transport Mechanisms
Dong Wang, Joshua A. Dijksman, Jonathan Bares +2
Shearing granular materials induces non-affine displacements. Such non-affine displacements have been studied extensively, and are known to correlate with plasticity and other mech…
Small Solar System Bodies as granular media
D. Hestroffer, P. Sánchez, L. Staron +12
Asteroids and other Small Solar System Bodies (SSSBs) are of high general and scientific interest in many aspects. The origin, formation, and evolution of our Solar System (and oth…
Multiscale Poromechanics of Wet Cement Paste
Tingtao Zhou, Katerina Ioannidou, Franz-Josef Ulm +2
Capillary effects such as imbibition-drying cycles impact the mechanics of granular systems over time. A multiscale poromechanics framework was applied to cement paste, that is the…
Shear jammed, fragile, and steady states in homogeneously strained granular materials
Yiqiu Zhao, Jonathan Barés, Hu Zheng +2
We study the jamming phase diagram of sheared granular material using a novel Couette shear set-up with multi-ring bottom. The set-up uses small basal friction forces to apply a vo…
Soft grain compression: beyond the jamming point
Thi-Lo Vu, Jonathan Barés
We present the experimental studies of highly strained soft bidisperse granular systems made of hyperelastic and plastic particles. We explore the behavior of granular matter deep…
Enlightening force chains: a review of photoelasticimetry in granular matter
Aghil Abed Zadeh, Jonathan Barés, Theodore A. Brzinski +10
A photoelastic material will reveal its internal stresses when observed through polarizing filters. This eye-catching property has enlightened our understanding of granular materia…
Jamming transition in non-spherical particle systems: pentagons vs. disks
Yiqiu Zhao, Jonathan Barés, Hu Zheng +4
We investigate the jamming transition in a quasi-2D granular material composed of regular pentagons or disks subjected to quasistatic uniaxial compression. We report six major find…
Seismic-like organization of avalanches in a driven long-range elastic string as a paradigm of brittle cracks
Jonathan Barés, Daniel Bonamy, Alberto Rosso
Very often damage and fracture in heterogeneous materials exhibit bursty dynamics made of successive impulse-like events which form characteristic aftershock sequences obeying spec…
