postdoc physics of fracture (Aalto, finlande)

Dear colleague,

My group is looking for a post-doc candidate in the physics of fracture.

The activities of the group in this regard concern experiments on complexity of fracture mechanics and models / theory to account for observed phenomena.

The position is financed by an Academy of Finland grant on time-dependent fracture. The goals of the post-doc position may be tuned towards the strengths and interests of the person hired, and the aspects may include participation in the design and running of experiments, analyzing experimental data, and focusing in computational models including writing code. An essential part is interacting with others in the group working in related areas.

The Complex Systems and Materials group is located in the Department of Applied Physics at the Aalto University, 10 km (15 min by metro) from Helsinki downtown. The duration of the position is 1+1 years. Post-doc candidates are expected to have a solid knowledge in statistical physics, and have an interest in some mixture of non-equilibrium physics, fracture, and complex systems.

Freeform, 1 page applications plus a CV and the contact info for 2-3 references should be sent by email to mikko.alava@aalto.fi by January 15th, 2019.

Best regards, Mikko Alava

Postdoc : Morphable structures with varying stiffness (ENS / ESPCI)

Annonce postdoc en pdf

We have a joint postdoc opening between the MecaWet lab @ PMMH and the Folding, Sliding and Stretching lab @ LPS in the area of controllable multi-component elastic structures, with a focus on experimentsThe goal is to design materials whose stiffness may be dynamically adjusted and to explore their use to rigidify morphable 3D structures.

A “baromorph” elastomeric plate morphing into a saddle shape under air suction (left) and into a cone upon inflation (right).

 

Description: By embedding channels within an elastomer we have recently developed structures that change shape under applied pressure. However, their softness hinders applications to large scales. Adding a more rigid component can rigidify the structure, but in a non-linear fashion. The project consists of designing and prototyping multi-component elastic materials with tunable rigidity. The general idea is to control the relative contributions of compliant and stiff components with a third active phase. The goal is to rationalize the fundamental aspects of the problem, to produce bulk materials and to design morphable / rigidizable structures. This multidisciplinary project is at the interface between structural mechanics, fluid dynamics, soft robotics and nonlinear physics.

 

Profile: Candidates should have recently obtained or are about to obtain a Ph.D. in Physics, Mechanical/Civil/Aerospace Engineering, or related disciplines. The project is primarily experimental but also includes some theory and numerical computations. On the experimental side, expertise in rapid prototyping, micro-fabrication, material science, and/or mechanical testing is welcome. In addition, an appreciation for scaling analysis, theory and computation is a plus.

 

Hosting teams: The successful candidate will participate in a collaboration between two laboratories who study problems in fluid and solid mechanics in conjunction with other disciplines: non-linear physics, instabilities, out-of-equilibrium statistical physics, multi-scaled phenomena, geomorphology, planetology… Their research involves a combination of laboratory experiments, theory and numerical simulations.

Although the project is fundamental in nature, we envision applications for medical equipment and, more generally in applied science.

The laboratories are both located in the Latin Quarter, in the center of Paris, which offers state-of-the-art facilities and a unique scientific environment.

 

Funding: Funding for one year is available (through an ANR grant) and we expect the candidate to help us find additional funding for a second year.

Reactive transport, mineral dissolution and precipitation in fractured and porous rock: experiments, models and field observations (session à EGU 2019)

j’aimerais faire la publicité d’une session que je co-organise à la prochaine assemblée de l’EGU à Vienne du 7 au 12 avril prochain:

https://www.egu2019.eu

Reactive transport, mineral dissolution and precipitation in fractured and porous rock: experiments, models and field observations
La date limite pour proposer un abstract est le 10 janvier 2019.

Numero de notre session : HS8.1.7 abstract:
Dissolution, precipitation and chemical reactions between infiltrating fluid and rock matrix alter the composition and structure of the rock, either creating or destroying flow paths. Strong, nonlinear couplings between the chemical reactions at mineral surfaces and fluid motion in the pores often leads to the formation of intricate patterns: networks of caves and sinkholes in karst area, wormholes induced by the acidization of petroleum wells, porous channels created during the ascent of magma through peridotite rocks. Dissolution and precipitation processes are also relevant in many industrial applications: dissolution of carbonate rocks by CO2-saturated water can reduce the efficiency of CO2 sequestration, mineral scaling reduces the effectiveness of heat extraction from thermal reservoirs, acid rain degrades carbonate-stone monuments and building materials.
With the advent of modern experimental techniques, these processes can now be studied at the microscale, with a direct visualization of the evolving pore geometry. On the other hand, the increase of computational power and algorithmic improvements now make it possible to simulate laboratory-scale flows while still resolving the flow and transport processes at the pore-scale.
We invite contributions that seek a deeper understanding of reactive flow processes through interdisciplinary work combining experiments or field observations with theoretical or computational modeling. We seek submissions covering a wide range of spatial and temporal scales: from table-top experiments and pore-scale numerical models to the hydrological and geomorphological modelling at the field scale. We also invite contributions from related fields, including the processes involving coupling of the flow with phase transitions (evaporation, sublimation, melting and solidification).

Rencontres Mécanique-Physique : matériaux actifs (Congrès Français de Mécanique – Brest Août 2019)

le Congrés Français de Mécanique se déroulera du 26 au 30 août 2019 à Brest et comprendra en particulier un Mini-Symposium (M1) – Rencontres Mécanique-Physique : matériaux actifs

DEADLINE pour les soumission : le 15 janvier 2019

M1 – Rencontres Mécanique-Physique : matériaux actifs

Christophe Eloy et Benoît Roman

Une carrosserie dont la forme change sous l’effet de la vitesse, des panneaux solaires qui suivent le soleil à la manière des tournesols… Voici des exemples de matériaux actifs « intelligents » dont la forme est modifiée par la pression, la température, l’humidité, etc. L’objectif de ce mini-symposium est d’avoir un aperçu de la recherche sur ces matériaux actifs, qu’ils soient naturels ou artificiels. Ils posent en effet des questions complexes de mécanique et de physique (grandes déformations, non-linéarités, couplages multi-physiques, instabilités).

Ce mini-symposium, à l’interface entre la science des matériaux, la mécanique des solides, les interactions fluide-structure et la biologie, abordera les thèmes suivants (liste non limitative) : la robotique souple, les matériaux programmables, l’extraction d’énergie de l’environnement, différents types d’actuation, la modélisation de la croissance et de la morphogenèse, etc.

Ce mini-symposium se place sous le double label de l’Association Française de Mécanique (AFM) et de la Société Française de Physique (SFP).

3. Participation is free. Only those intending to present a flask talk should register.

4. Deadline for registration (http://jstat.phys.ens.fr/) is on ** Dec 20 2018 **

5. Participants who subscribe for flash talks will be recontacted to upload their slides. The corresponding file will be sent in pdf format before Jan 14 2019

6. The programme will be available on Jan 17
