Our lab is always looking for motivated students wishing to discover computational solid mechanics through challenging research topics and/or practical applications. We try to provide unique project subjects, tailored to the student and related to research relevant to the laboratory, such as:
- fracture and damage mechanics
- numerical methods (finite elements, boundary elements, coupling methods, homogenization, etc.)
- structural analysis
- contact mechanics, tribology
- discrete and atomistic modeling
- high performance computing
- material modeling
- and many more…
The complete list of available projects can be found below shortly before each semester. We often engage in collaborations with other labs and universities. We are also open to suggestions for project topics. If you have an idea for a project you wish to do within our lab, don’t hesitate to contact us.
Master’s semester projects – Fall 2023
Earthquakes can be devastating, both in terms of human and material damage. Although their existence has been known since the dawn of time, the physics of earthquakes is still poorly understood. Natural faults and earthquake characteristics are known to follow scaling power-law. The origin of this phenomenon has strong implications on the physical mechanisms driving slip events. However, it is not yet clear. The emergence of complexity can be related to the disorder of the system. Understanding if the observed complexity comes from the inherent complexity of the frictional motion or the system’s complexity is essential to better understand – and one day eventually predict – earthquakes. It has been shown numerically with a simple system without any disorder that resulting slip events follow a power-law distribution for the small events – like natural slip events – and a log-normal distribution for the larger ones. This project aims to study how adding disorder in this simple system will influence the transition between the power-law and the log-normal distribution of slip events. To do so, the student will use a finite element software developed in the lab (Akantu).

Extreme loads on solids lead to the formation of a multitude of cracks that propagate, branch and coalesce to form fragments. This process is called dynamic fragmentation. This process is of importance in many domains of engineering, where it is fundamental to predict the outcome of high velocity impacts or explosions. Often, one would like to extract statistics such as fragment size distribution. This project will feature experiments on object breaking into pieces to extract experimental statistics on fragments. The student will then use a finite element software (Akantu) to simulate crack propagation using different methods such as phase-field modelling of fracture or cohesive elements. The statistics obtained numerically will be compared to the experimental ones to highlight the advantage and limitations of the different simulation methods.

The impact of a drop on a solid surface is a canonical problem in fluid mechanics of fundamental significance in numerous natural and industrial processes, such as ink-jet printing, aircraft icing and spray cooling. Recently we found out soft solids display a similar behavior when colliding with a rigid surface. Namely, the contact is not made on the tip, but on an annular radius, with air trapped in between. This project will explore the scenario of highly viscous droplets and soft solids impacting on each other. The student will use the finite element software (Comsol Multiphysics) to simulate the dynamics using knowledge of both fluid and solid mechanics. Depending on the interest of the student the project will focus either on full 3D simulations to capture symmetry breaking or on axisymmetric ones to investigate the feasibility of using level-set or phase field simulation for droplet-air interface.
