Students projects

We are developing a robust & fast boundary element code (in 2D and 3D) for elastostatic problems possibly including the presence of many cracks. Come & help us testing, documenting the code further by investigating different applied problem in solid mechanics.

We have acquired 10’000++ microCT scan images of fractured rock samples. Using a deep convolutional network, the fracture trace were picked. Come & analysis their statistics and what they tell us about fracture in quasi-brittle materials, and possibly in a second stage improve / re-train the neural network.

We recently  acquired a distributed fiber optic sensing system. In this project, you will investigate how from measure strain in a solid of known mechanical properties, you can reconstruct for the loading responsible for the measured strain.

The project combines experiments (mechanical testing with distributed strain sensing) and inverse problem modeling.

Pore-pressure and stress changes associated with sub-surface fluid injection / withdrawal can active fault slip. Finite element modeling of Thermo-hydro-mechanical problems.

 A concept to store seasonal heat in impermeable strata via the engineering of fractures, then hydrothermal loading / unloading cycles as a thermal battery. 
Explore the efficiency of such a concept using lab experiments and modeling.

Acoustic (active & Passive) monitoring of quasi-brittle materials (concrete, rocks) to image the evolution of damage & failures. Signal processing, Data analysis, seismological methods… come & learn geophysics applied to different kind of civil engineering problems….

Finite Element simulations of true triaxial reacting frame – including platen / samples friction etc.

Numerical modeling of soil-structures interaction problem for ULS. Students must have taken the Computational Geomechanics

In mobility @ Georgia Institute of Technology in collaboration with Prof. H Huang.

In this project, using recent advances in the distinct element modeling of quasi-brittle materials (Ma & Huang, 2018) such as rock and concrete, the goal is to reproduce numerically novel experiments designed to characterize the fracture mechanic behavior of these class of material. In particular, the goal will be to model the recently developed “gap-test” used to quantify concrete failure behavior (Bazant et al, 2022). This project requires a strong interest in the physics and mechanics of materials as well as numerical modelling.
