Micromechanical Study of Rock Fracture and Fragmentation under Dynamic Loads using Discrete Element Method

The study presented in this thesis aims to numerically explore the micro-mechanisms underlying rock fracture and fragmentation under dynamic loading. The approach adopted is based on the Discrete Element Method (DEM) coupled to the Cohesive Process Zone (C ...

A phenomenological analysis of Mode I fracture of adhesively-bonded pultruded GFRP joints

Thomas Keller, Anastasios Vassilopoulos, Moslem Shahverdi

The fracture behavior of adhesively-bonded pultruded joints was experimentally investigated under Mode I loading using double cantilever beam specimens. The pultruded adherends comprised two mat layers on each side with a roving layer in the middle. An epo ...

Electron Microscopy Mechanical Testing of Silicon Nanowires Using Electrostatically Actuated Tensile Stages

Reymond Clavel, Johann Michler, Jean-Marc Breguet, Dongfeng Zhang

Two types of electrostatically actuated tensile stages for in situ electron microscopy mechanical testing of 1-D nanostructures were designed, microfabricated, and tested. Testing was carried out for mechanical characterization of silicon nanowires (SiNWs) ...

3D strain map of axially loaded mouse tibia: a numerical analysis validated by experimental measurements

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann, Francesco Merlini, Vincent Forster, Jean Hocké, Jensen Verhelle

A combined experimental/numerical study was performed to calculate the 3D octahedral shear strain map in a mouse tibia loaded axially. This study is motivated by the fact that the bone remodelling analysis, in this in vivo mouse model should be performed a ...

Multi-axial mechanical properties of human trabecular bone

Liliana Rincon Kohli

In the context of osteoporosis, evaluation of bone fracture risk and improved design of epiphyseal bone implants rely on accurate knowledge of the mechanical properties of trabecular bone. A multi-axial loading chamber was designed, built and applied to ex ...

3D strain map of axially loaded mouse tibia: a numerical analysis validated by experimental measurements

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann, Francesco Merlini, Vincent Forster, Jean Hocké

A combined experimental/numerical study was performed to calculate the zone of highest strain in a rat tibia loaded axially. This study is motivated by the fact that the bone remodeling analysis in this in vivo rat model should be performed at the zone of ...

Pulse generator for trauma patient simulator

Madge Audrey Marie Martin

Developing a Trauma Patient Simulator is a very ambitious project that goes far beyond what can be expected for a master thesis. Therefore, it has been decided to focus on blood circulation which is one of the three vital functions described in the first a ...

Using predisposition factors for landslide hazard assessment: a new GIS-based methodology

Aurèle Parriaux, Séverine Bilgot

Switzerland is exceptionally subjected to landslides; indeed, about 10% of its area is considered as unstable. Making this observation, its Department of the Environment (BAFU) introduced in 1997 a method to realize landslide hazard map. It is routinely us ...
