European Solid Mechanics Conference (Bologne, juillet 2018)

Dans le cadre de  10th European Solid Mechanics Conference (juillet 2018, à Bologne),  le GDR participe à l’organisation d’un mini-symposium:
The past years have seen a renewed interest in the physics community for solid mechanics. Physicists, mainly condensed matter physicists, have started to revisit problems of mechanics and materials, thought to be classical by engineers and mechanicians. This renewed interest brought a research stimulus in the solid mechanics community. An example can be found in the theme of elastic structures where buckling, once thought as something to avoid, is now used to design and optimize systems: soft structures working in the post-critical regime are bringing new functionalities while still exhibiting excellent mechanical performances. Other examples can be found in biomechanics, the interplay between fluid and solids, growth and form, fracture mechanics.

The goal of this mini-symposium is to bring the solid mechanics and physics communities together for exchange of ideas, cross-fertilization, and new collaborations. We believe each community has its own tools and paradigms to bring: statistical physics on one side, and continuum mechanics on the other for example. We believe the emerging mechanics-physics community will be gathered around common tools (applied mathematics, nonlinear dynamics, proof-of-concept experiments, …) rather than a precise theme.

Mini-Symposium on Homogenisation, European Solid Mechanics Conference (Bologna, July 2018)

Mini-symposium description

Composite materials are considered in a very broad sense. A matrix phase can be reinforced/weakened with continuous fibers, short fibers, particles or platelets or even more phases. The matrix materials can be thermoset polymers, thermoplastic polymers, elastomers, gels, metals, concrete etc. The reinforcements can be continuous Carbon or ceramic fibers, short glass fibers, nanoclay particles, Carbon nanotubes, iron particles, multi-phase alloys (e.g., TRIP steels) among others. The effective response thus can be mechanical, electrical, magnetic, thermal or any combination of those, e.g., magnetoactive, electroactive, thermomechanical etc.

In addition, porous or micro-cracked materials are also viewed in this MS as « composites », where the matrix phase can contain micro-cavities or micro-cracks.

The present MS invites contributions for all the above-mentioned cases with an emphasis on the micromechanical, homogenization, scale-transition or multi-scale modeling methods that could also include experiments. Non-restrictive examples are the following:

– direct finite element simulations of representative volume elements;

– methods of cells, subcells and transformation field analysis;

– asymptotic or mathematical homogenization theory;

– mean-field homogenization methods;

– linking continuum mechanics at the matrix phase level and molecular dynamics or atomistic scale simulations at the levels of nano-particles or matrix/inclusions interphases or interfaces.

– homogenization of active composite materials such as magnetoactive or electroactive polymers, piezoelectric composites etc.

Emphasis is put on the nonlinear behavior such as nonlinear elasticity, plasticity, viscoplasticity, coupled elasto-viscoelasticity-viscoplasticity, damage, fatigue, etc., at small or large deformations.

Complex and Disordered Materials, World Congress on Computational Mechanics (New York, July 22-28, 2018)

A mini-symposium entitled “Mechanical response of complex and disordered materials” will take place 
at the 13th World Congress on Computational Mechanics to be held July 22-27, 2018 in New York City.

Abstract: This mini-symposium focuses on the small scale mechanical response of complex materials (disordered materials, glasses, granular media, beam lattices, fibreous materials, etc.) subjected to mechanical load. These materials exhibit complex inhomogeneous deformations, with strain localization and/or history dependence, yielding to unusual visco-plastic properties.
The application of numerical approaches for analyzing the response of the complex microstructure of disordered materials has resulted in a coupling between scales, with the goal of formulating a continuum description of the mechanical response at large scale from first principles. Such approaches include molecular dynamics simulations, smoothed particle hydrodynamics, coarse-graining methods, second-gradient or Cosserat modelization, and mesoscopic modelling.
The purpose of the meeting is to answer the following questions: How may one take into account the microstructure of such disordered materials? How much precision is required for adequately capturing particular properties? Is there a length scale dependence in the continuum description of such systems? What is the most appropriate way to transfer information from the lower to the upper length scale.
The mini-symposium will be organized into successive sessions, interspersed with time slots specifically devoted to thematic discussions.
It will promote interactions between participants from mechanical engineering, computational mechanics as well as condensed matter and statistical physics.

Green plants are Earth’s primary solar energy collectors, and the vision of enhancing plant productivity to ensure population- and food security in the 21st century has stimulated enormous scientific interest. Using breeding and genetic tools, the goal is to develop plants with enhanced ability to perform photosynthesis and distribute energy-rich sugars across the plant body. To succeed in this effort an in-depth understanding of the physical and biological constraints on sugar transport and resource allocation in plants is required. The sensitivity of plant cells, however, has hampered the development of experimental tools to reach this goal. This, combined with the lack of appropriate biomimetic models has made it exceedingly difficult to shed light on several highly important biological processes.

By bringing together scientists from different disciplines for an intense working group, we propose to catalyze advances in elucidating basic mechanisms and constraints on sugar transport in plants. We will bring together leading and emerging researchers – as well as students – from plant physiology and genetics, physics, and engineering, in a 2-day workshop. Our goal is to create an interdisciplinary environment that can address key fundamental questions at the interface between physics, physiology and molecular biology, with strong impact on future crop development programs, as well as bioinspired systems.

We look forward to an inspiring meeting in Copenhagen.

Best wishes,
Kaare H. Jensen, Missy Holbrook and Michael Knoblauch

Meeting on rheology of multiphase geological materials – 18/19 Dec 2017, Bristol

This year’s British Society of Rheology Midwinter meeting will be held on 18/19th December in Bristol. 
 
The theme of the meeting is « Rheology and flow of multiphase geological materials » and the goal is to open a dialogue between the geo-rheo community and the broader rheology community – hopefully to the benefit of both. 
 
We will be focussing particularly on the rheology of multiphase magma, and the rheology of granular flows. 
 
You can read more about the meeting here:
