Full textA multi-scale approach introduces a structural zoom method into a region of interest, called the patch, using only field projection operators. The different behaviours in the patch and in the overall structure are taken into account without using weight parameters between local and global energies such as the Arlequin method. Our initial problem is to digitally reliable the structural zoom method for the linear case, and more precisely to choose a high-performance solver on Krylov spaces, as well as effective preconditioning and ordering adapted to the system to be solved. Once the solver is chosen, this approach is mechanically validated in the mean of two tests, namely traction and shear. A parametric study of the patch is performed to obtain an acceptable solution. The next objective is to extend this approach to regions with heterogeneities of non-linear behaviour. The method has been reached out for elastoplastic behaviour. Initial hypothesis assumes the elastoplastic behaviour only inside the patch and an elastic behaviour of the overall structure as well as of the gluing area. Finally, this approach is validated with different tests including several faults and therefore several patches as well as different loading history

Full textThe permeability of rocks is widely affected by the presence of fractures as it establishes prevailing paths for the fluid flow. Natural cracks are then a critical factor for a reservoir productiveness. For low permeability rocks, stimulation techniques such as hydrofracturing have been experienced to enhance the permeability, so that the reservoir becomes profitable. In the opposite, when it comes to geological storage, the presence of cracks constitutes a major issue since it encourages the leak and migration of the material spread in the rock. In the case of CO2 storage, the scenario of leakage across the reservoir seal through cracks or revived faults is a matter of great concern. And as for nuclear waste storage, the fluid circulation in a fracture network around the storage cavity can obviously lead to the migration of toxic materials. It is then crucial to predict the effects of the presence of cracks in a reservoir. The main purpose of this work is the design of a numerical tool to simulate a crack network and its evolution under hydromechanical loading. To achieve this goal we chose the eXtended Finite Element Method (XFEM) for its convenience, and a cohesive zone model to handle the crack tip area. The XFEM is a meshfree method that allows us to introduce cracks in the model without necessarily remeshing in case of crack propagation. The fluid flow in the crack as well as the exchanges between the porous rock and the crack are accounted for through an hydro-mechanical coupling. The model is validated with an analytical asymptotic solution for the propagation of a plane hydraulic fracture in a poroelastic media, in 2D as well as in 3D. Then we study the propagation of hydraulic fractures on non predefined paths. The cracks are initially introduced as large potential crack surfaces so that the cohesive law will naturally separate adherent and debonding zones. The potential crack surfaces are then updated based on a directional criterion appealing to cohesive integrals only. Several examples of crack reorientation and competition between nearby cracks are presented. Finally, we extend our model to account for the presence of fracture junctions

Full textTo decrease product design time, we propose a decision making method in distant concurrent engineering. We have built and applied a loop method of decision making in product design which integrates the internal and external teams of the company, including customer. The various product concepts must be spread by the internet. They are proposed according to " virtual intermediate representations " that we characterize using our " 3i model " (information, infrastructure, interoperability). In order to evaluate different product concepts through the internet, we develop a conjoint analysis software using virtual prototypes
