Best wishes for 2022

Dear ALERT community,

The ALERT Bureau and the Board of directors would like to wish you a happy new year 2022.

The year 2021, although far better than 2020, was still under the influence of the Covid-19 pandemic. Nonetheless, we had the chance to meet in person in Aussois. This year’s edition was organized in a hybrid mode, with presenters and participants being able to access the workshop and doctoral school remotely. It allowed a greater number of participants, which is great! 

We hope that 2022 will allow us to further develop and strengthen the ALERT community, whatever the restrictions associated to Covid-19.

We wish you all the best for 2022,

See you all in Aussois.

ON-SITE FULLY BOOKED & SANITARY UPDATE – ALERT Workshop & School 2021

Dear ALERT community,

As you may know, the registration for the ALERT Workshop and School 2021 is open! The preliminary program of the Workshop and School is available here.

It was decided to propose you two alternatives for your registration to the workshop and doctoral school: either you can come and participate in Aussois, or you can attend those remotely.

UNFORTUNATELY, the number of participants that can come to Aussois is limited to 160, and has been reached. The only registration possible from now on is therefore remotely.

ABOUT THE SANITARY CONDITIONS

As a reminder, the restrictions for entering France will depend on your country of departure and your vaccination status (more information here and here).

Your stay (and access) at the CNRS “Centre Paul Langevin” where the event takes place is conditional on the presentation of a HEALTH PASS upon your arrival. This means that you must have at least one of the following documents:

  • A vaccination certificate (provided you have a complete vaccination schedule);
  • A negative test (RT-PCR or antigen of less than 48 hours). For unvaccinated travelers from Cyprus, Spain, Greece, Malta, the Netherlands and Portugal, a negative PCR or antigen test of less than 24 hours is required;
  • A certificate of recovery from Covid-19 (RT-PCR or positive antigen test dated at least 11 days and less than 6 months).

More information can be found here. For members of “green list countries” (see the website), a sworn statement attesting to the absence of symptoms of covid-19 infection and contact with a confirmed case of covid-19 is also required. You can find it here.

Furthermore, the center has implemented a strict health protocol, providing for the wearing of masks in all premises and common areas in order to guarantee the safety of all. The full health and safety protocol can be accessed here, please read it before your arrival.

LAST REMINDER

Please read the hints in the registration form! After filling the form and pressing the button “Register”, a window will open with your invoice. Please print the window with the invoice for your records! You will also get an email with the registration data afterwards. If you are an ALERT members, the corresponding representative of your ALERT institution will receive the registration data too.

The deadline for the registration is the September 17th! 

Looking forward to (safely) meeting you in Aussois!

Presentations of the ALERT Doctoral School 2021

ALERT Doctoral School 2021
30th September to 2nd October 2021, Aussois, France (or online)

Constitutive Modelling in Geomaterials
Coordination: prof. Claudio Tamagnini [CT] and prof. David Mašín [DM]
Lecturers: prof. Ivo Herle [IH], prof. Cristina Jommi [CJ] and prof. Claudio di Prisco [CDP]

Foreword

Irrespectively of fast development of approaches for the analysis and design in geomechanics based on the methods for discontinuum (such as discrete element method), analysis of continua based on mesh or fast developing particle-based meshless methods still represents major means of numerical analysis in geomechanics. At the very core of such an analysis is a constitutive model: mathematical relationship converting the peculiar behaviour of particulate material, governed by the interactions between individual particles, into the behaviour of continua. As such, a properly selected and calibrated constitutive model has a critical effect on the outcomes of geotechnical simulations.

This school aims to introduce the students into the broad field of constitutive modelling of particulate materials with special emphasis on the behaviour of soils: after the introduction consisting of summary of basic features of soil behaviour, they will be introduced into fundamentals of constitutive modelling, followed by more detailed description of various modelling approaches – from the basic elastic and elasto-plastic models to more advanced frameworks of hardening plasticity, bounding surface plasticity, generalised plasticity and hypoplasticity. The second day will be focused on various specific more-advanced topics, such as simulation of small strain stiffness and cyclic loading, modelling of unsaturated soils, meta-stable structure, breakage, thermal effects, chemical effects and time and rate dependence, including formulation of finite-deformation plasticity and macroelement modelling. The last day is devoted to steps needed for adoption of models in numerical analysis tools, namely to their implementation in finite element codes. Finally, in practical hands-on sessions, students will train calibration using real experimental data themselves, using both manual and automatic freely-available calibration tools.
