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.

Day 1

  • Basic features of soil behaviour and soil testing [CJ]
  • Fundamentals of constitutive modelling for soils [IH]
  • The theory of plasticity in constitutive modelling of rate-independent soils [CT]
  • Hypoplasticity and other incrementally non-linear modelling approaches [DM]

Day 2

  • Modelling non-linearity, small-strain stiffness and cyclic loading [DM]
  • General overview on modelling the coupled behaviour of unsaturated soils [SJ]
  • Meta-stable structure, breakage and thermal effects [DM]
  • Time and rate dependence [CDP]
  • Finite deformation plasticity [CT]

Day 3

  • Numerical implementation of constitutive models [CT]
  • Macroelement modelling [CDP, Luca Flessati]

Dear ALERT Geomaterials community,

I hope you are all keeping well!

This is a wee reminder that the abstract submission for the 14th Euroconference on Rock Physics and Rock Mechanics has been extended to the 4th of July 2021.

To submit your abstract, please follow the instructions:

https://www.euroconference2021.org/Submit

Moreover, the registration has now opened and you can register until the 20th of August 2021. You can find more info on our website:  https://www.euroconference2021.org/.

We are looking forward to meeting you virtually on the 30th of August!

Best wishes,

Elma (on behalf of the organising committee).

Workshop and Doctoral School announcement

Dear ALERT community,

As sanitary conditions are improving, certainly thanks to the vaccination, we are confident that it will be possible to meet again in September 2021 in Aussois.

However, it cannot be ruled out that travel restrictions will still be in place at that time, particularly from outside the EU. The conditions for entering France will depend on your country of departure and your vaccination status (https://www.diplomatie.gouv.fr/en/coming-to-france/coronavirus-advice-for-foreign-nationals-in-france/#sommaire_1 ).

Therefore, for the first time in the history of ALERT, the decision was taken to organize the workshop and the doctoral school in hybrid mode in 2021. It means it will be possible to attend these events while being present in Aussois or remotely. This way, we hope to meet the expectations of both those eager to meet and those unwilling to travel.

In the coming weeks, you will be able to register and choosing one of these two options (which can be modified if necessary).

Keep staying safe, long life to ALERT-Geomaterials!

The Center of Excellence on Subsurface Mechanics and Geo-Energy at the Indian Institute of Technology Madras is delighted to present a summer webinar series titled Advances in Subsurface Mechanics for Energy and Environment – 2021 (ASMEE – 2021). The webinar series will be held on Fridays in the months of July – September 2021.

The webinars will host leading researchers from academia and industry to discuss pioneering research in the broad area of subsurface mechanics. The choice of topics is diverse and is expected to include experimental and computational geomechanics, multiphase flow and reactive transport modeling, subsurface characterisation, geochemistry, and their applications in oil & gas and geothermal energy industries.

The talks are open to all; however, registration is mandatory. Details of each presentation will be sent one week prior to all registered participants. More information on upcoming webinars and registration can be found here: https://civil.iitm.ac.in/pcoe/smge/.

Advanced course on Modeling of Localized Inelastic Deformation (LID 2021),
taught by Milan Jirásek in Prague, Czech Republic, 6-10 September 2021.

This course provides an overview of modeling approaches used in the mechanics of inelastic materials and structures, with special attention to objective description of highly localized deformation modes such as cracks or shear bands. It is one of the RILEM educational courses. The course is intended for graduate students at the doctoral level, but it can be equally useful to motivated master students, post-doctoral researchers, or senior researchers who are not specialists in this field.

For details see http://mech.fsv.cvut.cz/~milan/course2021.html
For registration please contact Milan.Jirasek@fsv.cvut.cz .

OOFEM course in Prague, Czech Republic, 13-15 September 2021

Moreover, the Department of Mechanics, Faculty of Civil Engineering, Czech Technical University in Prague, has prepared a training course for Ph.D. students, engineers interested in simulation and researchers who wish to quickly acquire the knowledge and practical skills necessary to employ OOFEM (an object-oriented open-source software package for solid mechanics, with extensions to fluid mechanics and transport problems). Participants will learn how to create, analyze and post-process models. Moreover, they will understand the OOFEM code structure and they will learn how to implement custom material models, elements, boundary conditions, or solvers.

The course takes place in Prague on 13-15 September 2021 and it will be delivered by a team of skilled OOFEM developers. No prior knowledge of OOFEM is required; however, a basic knowledge of C++ is highly recommended.For details see http://www.oofem.org/en/courses
Registration can be done by filling an online form.
Questions should be addressed to oofem@fsv.cvut.cz.
