Near the dripline, where the energy needed to remove one nucleon is low enough or even negative, neutron emission from neutron-rich nuclei is a characteristic phenomenon. Ground state two-neutron decays are a special case that may occur once we go beyond the dripline. The spectroscopy and neutron decay of the most neutron-rich isotopes of Beryllium...
Cette recherche se base sur l’établissement de différents critères de flexibilité professionnelle lors du changement de prescription en 2011 par les enseignants de Sciences Industrielles de l’Ingénieur et sur la comparaison des méthodes de modélisation de l’énergie entre la Technologie et les Sciences Physiques. La méthodologie utilisée dans la thè...

The purpose of this retrospective study is to evaluate the accuracy of soft tissue prediction models with Dolphin Imaging. Preoperative and 1-year postoperative Lateral cephalograms (LCG) of patients undergoing Le Fort I, bilateral sagittal split osteotomy (BSSO) or bimaxillary osteotomy (Bimax) between 2006 and 2009 were retrospectively collected....
The objective of this work is to demonstrate the efficiency of advanced elastoplastic constitutive equations strongly coupled with isotropic ductile damage in the framework of the micromorphic continua in order to overcome the mesh dependency in the prediction of the ductile cracks initiation and propagation. This approach is based on (i) the intro...
The quality of protective oxide scales developing at the metallic alloys surface at high temperature depends on the stress generation and relaxation mechanisms. In this work, a model and a related identification tool have been developed in order to investigate the stress evolution in the metal/oxide systems under thermal cycling loadings, along wit...
The aim of this thesis is to propose two complementary approaches for modeling and numerical simulations of thin sheet metal forming processes. The first one is a deliberately simplified multi-step inverse approach to simulate and "optimize" rapidly and inexpensively thin-sheet stamping processes while maintaining good accuracy in the stress calcul...
The thesis is dedicated to the study of elasto-plastic behavior of multiphase polycrystalline materials and ductile damage at different scales. The microscopic heterogeneities have important influence on the macroscopic mechanical behavior of materials. Ductile damage is still difficult to measure at small scales. The following issues are the main ...
Wind erosion process can lead to several environmental consequences: desertification, land degradation, air pollution, etc. This last one is related to particulate matter emissions from granular materials commonly found on industrial sites, such as ore and coal. The particle size distribution of these granular materials usually consist of a mixture...
Elasticity, viscoelasticity and glass transitions of glass-forming liquids and model solids are investigated by computer simulations at equilibrium using the stress fluctuation formalism. The models systems studied include Lennard-Jones systems at two and three dimensions, a binary mixture of Lennard-Jones (LJ) particles constituting the two-dimens...
