Elastoplastic description of sudden failure in athermal amorphous materials during quasistatic loading

Matthieu Wyart, Thomas Willem Jan de Geus, Marko Popovic

The response of amorphous materials to an applied strain can be continuous or instead discontinuous if the initial configuration is very stable. We study theoretically how such a stress drop emerges as the system's initial stability is increased. We show t ...

3D dynamic fragmentation with parallel dynamic insertion of cohesive elements

Jean-François Molinari, Nicolas Richart, Marco Vocialta

Dynamic fragmentation is a rapid and catastrophic failure of a material. During this process, the nucleation, propagation, branching, and coalescence of cracks results in the formation of fragments. The numerical modeling of this phenomenon is challenging ...

Time-dependent failure analysis of large block size riprap as bank protection in mountain rivers

Mona Jafarnejad Chaghooshi

The protection of riverbanks with blocks, called riprap, is the most used method in alpine rivers to avoid uncontrolled lateral erosion. For rivers with significant bed slopes large boulders have to be used in order to withstand high flow forces. Such larg ...

2D to 3D dynamic fragmentation with parallel cohesive elements

Jean-François Molinari, Nicolas Richart, Marco Vocialta

Dynamic fragmentation is a fast and catastrophic failure that takes place when an extreme load is applied to a material. During this process complex crack patterns develop. Cracks initiate at internal micro-defects, they propagate, eventually branch, and f ...

Effect of compressed riprap thickness on the stability of river banks

Anton Schleiss, Michael Pfister, Mário Jorge Rodrigues Pereira Da Franca, Mona Jafarnejad Chaghooshi

One of the common measures for river bank protection is the installation of riprap. There are several methods to design riprap appropriately, which are however generally limited to dumped medium size blocks. Nevertheless, an additional resistance against e ...

Full-waveform GPR inversion to assess chloride gradients in concrete

Eugen Brühwiler, Alexis Kalogeropoulos

The spreading of deicing salt on roads during winter and the consequent migration of chloride ions within concrete exposes structures reinforcement to corrosion. Reinforcement corrosion is problematic because it reduces the structure's load carrying capaci ...

Numerical study of the heating-cooling effects on the geotechnical behaviour of energy piles.

Lyesse Laloui, Fabrice Dupray, Alice Di Donna

Energy geostructures represent a renewable and clean source of energy which can be used for heating and cooling of buildings and de-icing of infrastructures. This technology couples the structural role of geostructures with the energy supply, using the pri ...

Time Dependent Failure Analysis of Compressed Riprap as Riverbank Protection

Anton Schleiss, Michael Pfister, Mona Jafarnejad Chaghooshi

Riprap is a common measure for protecting river banks against lateral erosion and several methods exist to design them. However, they are generally limited to dumped medium size rocks. If large rock blocks are required for stability reasons, they cannot be ...
