Dear colleagues,

we organize a symposium Mechanics of Soft Materials and Structures during the European Mechanics of Materials Conferences (EMMC) to be held may 27-29th 2020 in Madrid. The EMMC is a series of biyearly meetings organized under the auspices of the European Mechanics Society, Euromech, that has taken place during the last 25 years. The conference will be a meeting point of researchers with common interests in mechanics of materials from different perspectives including mechanical engineering, physics, biomechanics, applied mathematics, chemistry, etc…

S5: Mechanics of Soft Materials and Structures

Soft mechanical systems can derive their compliance either from the constitutive nature of the underlying low-modulus materials or from the slender geometry of their structural members (even with high-modulus materials). The mechanics of soft materials and structures is currently the focus of renewed research efforts taking advantage of quickly evolving experimental techniques for design, fabrication, and characterization, as well as novel theoretical and computational tools for analysis. The combination of the development of new materials with unprecedented mechanical properties, together with modern manufacturing techniques (e.g., molding, lithography, and 3D printing) to realize complex architectural layouts, are opening a wide array of opportunities, both for research and applications. For example, soft materials may be activated by coupling mechanical deformation with electrostatic, physical-chemical, magnetic or fluid forces. Such material systems are, therefore, promising candidates to envision as active structural components necessary soft robotics, shape-morphing structures, and compliant energy-harvesting devices. Soft materials also share comparable mechanical properties and, often, constitutive composition with biological tissue, therefore, acting as valuable model systems for their mechanical behavior. Another specificity of soft mechanical systems is the relative importance of surface forces such as adhesion, and capillary effects, which may even become dominant.

This session aims at bringing together researchers sharing an interest in the mechanics and physics of soft materials and structures, which, despite diverse, share the common fundamental challenges of nonlinear mechanics (large strains, nonlinear constitutive behavior, and geometric nonlinearities) coupled with other intricate physical mechanisms.

Tec 21 Winter school on  « Multi scale approaches and multiphysics couplings in fluid and solid mechanics »  (4th Edition)
Grenoble – 20th to 24th January 2020
Objectives:  Important societal issues require to solve problems in mechanical and process engineering of increasing complexity. A key vector of progress relies on multi-scale and multi-physics approaches. The aim of this summer school is to make an overview of the different approaches, numerical and experimental techniques allowing to tackle this complexity. All the courses will be illustrated through various recent examples. Two days will be dedicated to practical exercises on « high tech demonstrators » based on the most up-to-date techniques and methods developed by partner laboratories of Tec21. Finally on Friday, invited lecturers will give a focus on «waves in fluids and solids ».

Dear colleagues,I would like to draw your attention to the focus session  » Wetting and Adhesion of Soft Materials : Dynamics and Instability » at the upcoming APS March Meeting, March 2-6, Denver, CO. The invited speaker is Etienne Barthel, ESPCI Paris. A description of the scope of the session can be found at the end of this email.

Deadline for abstract submission is Friday, October 25, 2019. Abstracts can be submitted here.
To ensure placement in the correct session, you should select the focus session :02.01.02 Wetting and Adhesion of Soft Materials: Dynamics and Instability (DSOFT, DPOLY, GSNP) [same as 01.01.31, 03.01.44]
Please feel free to pass on this information to anyone who might be interested.
I am looking forward to seeing you in Denver!
Best regards,Julien

02.01.02 Wetting and Adhesion of Soft Materials: Dynamics and Instability (DSOFT, DPOLY, GSNP) [same as 01.01.31, 03.01.44]

The wetting and adhesion properties of soft materials are relevant for a wide range of applications including antibiofouling and hydro/omniphobic coatings, medical dressings, water harvesters, microfluidic and MEMS/NEMS devices. In many situations, the macroscopic properties crucially depend on the physical processes localized near a line (contact line, fracture, triple line, etc…) where the two materials and a liquid/gas phase meet. The adhesion of linear elastic solids and the wetting of Newtonian fluids on homogeneous hard substrates are two ideal cases that have been studied intensively, yielding models bridging macroscopic linear behavior with contact line dynamics. Yet, beyond these idealized cases, many open questions arise concerning the local dissipative processes operating in the dynamical regimes. 

New and exciting applications in wetting and adhesion rely heavily on the complex rheological properties of fluids and soft solids, mechanical behavior at large deformations, and surface patterning. In the regimes of interest, the triple line is subjected to complex dissipation mechanism either localized near the contact line through steady stade motion or through spontaneous and noise-induced instabilities (stick-slip, avalanches, cavitation, pearling) at a mescoscale. While many efforts have been made over the last few years to capture these phenomena, our understanding is still very limited. This focus session aims at bringing together experimentalists and theoreticians.
