Modeling of Localized Inelastic Deformation, Prague, Czech Republic - From 18 September 2017 to 22 September 2017
This course provides an overview of modeling approaches used in the mechanics of inelastic materials and structures, with special attention to the objective description of highly localized deformation modes such as cracks or shear bands. It is organized as one of the RILEM educational courses. In 2016 it attracted 23 participants from 10 European countries and the United States.
Introduction: notation, fundamentals of tensor algebra, basic types of inelastic material behavior, principles of incremental-iterative nonlinear analysis.
Elastoplasticity: physical motivation, basic equations in one dimension, extension to multiaxial stress, associated and nonassociated plastic flow, hardening and softening, tangent stiffness.
Damage mechanics: physical motivation, basic equations in one dimension, isotropic damage models, smeared crack models, brief comments on anisotropic damage models, damage deactivation due to crack closure, combination of damage and plasticity.
Strain localization: physical aspects, structural size effect, conditions of stability and uniqueness, discontinuous bifurcation, incipient weak discontinuity, localization analysis based on acoustic tensor, loss of ellipticity and its mathematical and numerical consequences, classification of models for localized inelastic behavior, mesh-adjusted softening modulus (crack band approach).
Regularized continuum models: classification of enriched continuum theories, nonlocal formulations of the integral type, explicit and implicit gradient damage and plasticity formulations, phase-field approaches, continua with microstructure, localization analysis, implementation aspects, application examples.
Strong discontinuity models: brief introduction to finite elements with embedded discontinuities.

Multiscale Modelling Course for Concrete (MMC2), Delft, The Netherlands - From 02 October 2017 to 06 October 2017
RILEM MMC Multiscale Modelling Course for Concrete will be organized at the TU Delft, The Netherlands and is scheduled from: Monday October 2 to Friday October 6, 2017
Addressing lectures for macro- to nano- scale modelling.
Theoretical and practical workshops on multi-scale modelling.
Modelling mechanical, physical and chemical behaviour at different scale levels.
Emphasizing different approaches of modelling and how “numerical gaps” can be bridged.
Lecture material consists of a USB-stick containing all slides in PDF as presented during the course, literature, practical examples, a copy of the basic software that will also be used during the practical sessions.
The MMC2 course is designed for:
• Graduate students (PhD, MSc students and Postdocs)
• Professors and other academic professionals
• Professionals from industry
The course is intended for people working in areas where modelling knowledge of cement based materials can give you the edge in understanding problems and finding solutions.
• Conference date : From 02 October 2017 to 06 October 2017

Fiber reinforced concrete design aspects specifications, Bento Gonçalves, Brazil - From 31 October 2017 to 01 November 2017
The PhD course is open to international students.
The course is based on, but not limited to, the design recommendations of the fib Model Code 2010 (MC 2010). It is divided in eight sessions, as follows:
1. General introduction to FRC:
Brief history of FRC evolution; Fibers role; Examples of applications; Advantages of fiber incorporation; New materials: HPFRC and UHPFRC
2. Material properties:
Types of fibers; Fibers alignment and distribution; Casting procedures; Material response.
3. Mechannical properties:
Standards for test methods; Compressive, tensile and shear properties; Classification and constitutive modeling.
4. Design aspects of FRC:
Durability; FRC modeling approaches; Fracture and damage parameters; Cyclic (fatigue) and static loading; Tension stiffening; Closed form moment-curvature expressions
5. Shear and flexural design:
FRC behavior in bending and shear; Flexural and shear design aspects of plain and reinforced concrete with fibers.
6. Time dependent effects:
FRC creep behavior in tension and compression; Shrinkage.
7. FRC under fire:
Material properties evolution during fire; Creep effects during a fire scenario; Numerical modeling; Empirical formulations for the prediction of concrete deformations during heating.
Classification and characterization of FRC materials with different fiber amounts; Blind tests on RC beams with steel fibers.
The official language is English with simultaneously translation to Portuguese.
The participants of the course should register to the 59th Brazilian Congress on Congress through the website of the 59th IBRACON Congress on Concrete (link in the top right corner).
