post-doc : analytical, numerical and experimental study of uniform elastic rods (EPFL)

Assistantship in the Maddocks group at the EPFL http://lcvmwww.epfl.ch

A position is available to work on a combined analytical, numerical and experimental study of uniform elastic rods in two contexts:

1) the characterisation of helical equilibria, including stability properties, in both the cases of self-avoiding and self-contacting configurations,

and

2) the equilibria of knots in the presence of friction.

The first project will be carried out in collaboration with the group of Prof J. Kolinski (emsi.epfl.ch) and the second in collaboration with the group of Prof Pedro Reis (fleXLab: Flexible Structures Laboratory)

Preferences will be given to applications at the postdoctoral level, although doctoral level applications will also be considered. Review of applications will start April 15 and will continue until the post is filled. The position is available immediately, with the desired starting date being as soon as practicable, with December 2018 being the latest possible start date.

The application procedure and further information is described at http://lcvmwww.epfl.ch/jobs.php

ATELIER MePhy Instabilités en Mécanique du Solide le 16 mai 2018

Instabilités en Mécanique du Solide / Instabilities in Solid Mechanics

Le but de ces journées est de faire le point sur les études actuelles de stabilité de systèmes en mécanique des solides. Il s’agit tout d’abord de caractériser ou détecter une perte de stabilité et le mode instable correspondant, et éventuellement de contrôler ou de retarder l’instabilité. Mais on peut aussi chercher à utiliser une instabilité pour permettre d’actionner, d’imposer un motif particulier, de modifier la réponse non-linéaire, etc..

The aim of this workshop is to bring together and foster the discussion between communities dealing with instabilities in Solid Mechanics. The research on instabilities in Solid Mechanics is very currently very active: In some cases, the aim is to determine, prevent or control the stability of a system; In a different stream of research, the idea is to use an unstable behaviour (to trigger a spatial pattern, or a non-linear mechanical response).

The School is aimed primarily to PhD students, postdocs, and other young scientists wishing to broaden and deepen their knowledge or to identify new research opportunities.
A strong emphasis is put on basic concepts with several classes reviewing classical mechanics and physics. In order to keep the lectures as tutorial as possible, the 20 academic lecturers will give 1-3 talks.

The school will include

  • Main lecture courses (1h20 long, including questions).
  • Some « experimental lectures » based on a series of table-top experimental demonstrations by the speakers, with experiments available to the students during coffee breaks.
  • flash presentations for posters, and poster sessions.
  • ample time for discussion (coffee breaks, meals, and a long afternoon break)

Classes will start on August 7th in the morning and end on August 17th.

6th Southern Workshop on Granular Materials (Chile, 3-6 December 2018)

Dear Colleague,

We are pleased to invite you to participate and submit an abstract to the 6th Southern Workshop on Granular Materials (SWGM6). The conference will be held in Puerto Varas, on December 3-6, 2018. The SWGM6 will comprise a broad range of granular-system subjects providing an up-to-date view of the field in topics such as non-local rheology in granular flow, discharge flows, soft and non-spherical particles, shear-thickening suspensions, active macroscopic particles, impact on granular beds, propulsion in granular media, invasion phenomena, among others.
The SWGM6 will take place in the Hotel Cabañas del Lago at the city of Puerto Varas on the shores of Lake Llanquihue. Puerto Varas is famous for its architecture that uniquely combines its German heritage with a breathtaking landscape. The city is surrounded by beautiful sites, such as the All Saints Lake, the Petrohué Falls, the Osorno Volcano, Puerto Montt and Chiloe island.

Active Fluids and Crowd Motions (Days of condensed matter – Grenoble 27-31 aout)

Dear colleagues,
Please find attached the announcement of our mini-colloquium « Active Fluids and Crowd Motions » as part of the Days of Condensed Matter to be held in Grenoble from August 27 to 31. If you want to make a communication, you can already upload your abstract:

Abstract Submission: Choose MMH3 Active Fluids and Crowd Motions

You can also register on the same site.

MECHANICS OF SLENDER STRUCTURES IN PHYSICS, BIOLOGY, AND ENGINEERING:
FROM FAILURE TO FUNCTIONALITY
SOLVAY WORKSHOP 27-29 AUGUST 2018 (ULB, BRUSSELS, BELGIUM)
SCOPE:

During the past decade, mechanical instabilities were exploited to design new classes of functional mechanisms making use of the geometrically nonlinear behavior of their post-buckling regimes. Using flexible structures is nowadays considered as a promising route to create devices with novel modes of functionality or metamaterials with tailored properties such as foldable 3D objects obtained from 2D sheets by combined origami and Kirigami, flexible/stretchable electronics, bioelectronics or soft actuators for robotic applications, etc. This shift in thinking leads also to new developments in biology, where slender and flexible structures are ubiquitous, such as a better understanding of the morphogenesis of organs, the motion and the shape of plants or the locomotion of aquatic animals.

The ambition of this meeting is to bring together internationally acclaimed experts as well as young researchers in mechanics, biomechanics, biolocomotion, material science and architecture to address the current scientific challenges in these various fields. The workshop will serve as a platform to stimulate discussions, to start long-term scientific collaborations and to promote progress at the porous boundaries between these research domains.

TOPICS:

Ø Elastic Instabilities of Slender Objects

Ø Foldable Structures/Origami/Kirigami

Ø Elasto-capillarity/Fluid-Structure Interaction

Ø Biomechanics

Ø Bio-Inspired Robotics/Stretchable Electronics

procédés et matériaux pour l’impression 4D (Nancy 29 mars 2018)

Le domaine de l’impression 4D, avec quelques milliers de publications, émerge et dispose déjà de promesses extraordinaires (avec en particulier en ligne de mire l’impression 4D du vivant ou Bio-Printing)… Mais dans le fond, les publications récentes attestent encore des formes d’induction ou plus prosaïquement de « bricolage savant » dans un domaine en émergence correspondant à l’apparition d’un sentiment de rupture technologique dans lequel la créativité, les sciences chimiques (biologiques) et les procédés de l’ingénierie prennent une place importante.

Après avoir rappelé ce que représentent les principes de l’Impression 4D, la parole sera donnée à des spécialistes des différents domaines concernés par le « 4D Printing » avec en fin de réunion la mise en place d’un débat approfondi avec les participants.
