Full textThis thesis presents the development of an engineering method for the modelling of large strain nonlinear thaw consolidation. The work presented herein follows existing thaw consolidation theories and models. The foundations of one-dimensional thaw consolidation theory are therefore used. First, a numerical model for large strain nonlinear thaw consolidation is formulated by combining the Gibson large strain consolidation theory to heat transfer equations. The two components are coupled in a modelling domain formulated in Lagrangian coordinates that adapts to the soil deformation. This results in the introduction of a second moving boundary at the soil surface to model thaw consolidation in addition to the moving boundary at the thaw front. The model uses nonlinear σʹv – e – kv relationships to define the properties of thawed soils. A case study of the Inuvik experimental pipeline with the numerical model is presented. The case study demonstrates the use of the model for a practical problem and it is used to validate the model. The modelling results are compared to the results obtained with the small strain linear thaw consolidation theory and with the field data. The results obtained with the large strain nonlinear model for thaw settlement, the rate of thaw settlement and the excess pore pressures compare favourably with the field data. Second, a conceptual model for thaw consolidation of thawed fine-grained soils is proposed. The model is used to define the characteristics of the nonlinear σʹv – e – kv relationships used as input for the numerical modelling of thaw consolidation. The concept of the residual stress is generalized to ice rich soils by specifying that it is the effective stress within the soil element rather than the effective stress of the bulk soil. Then, empirical relationships are formulated to determine the characteristics of the σʹv – e – kv relationships as a function of the initial thawed void ratio and soil index properties.

Full textAs the pre-impregnated thermoplastic composites have recently attached increasing interest in the automotive industry for their excellent mechanical properties and their rapid cycle manufacturing process, modelling and numerical simulations of forming processes for composites parts with complex geometry is necessary to predict and optimize manufacturing practices. This thesis is devoted to modelling and simulation of the consolidation behavior during thermoplastic prepreg composites forming process. A new seven-node prismatic solid-shell element is proposed: six located at the apexes and the seventh sited at the center. A shear stain field is assumed to subdue transverse shear locking, the enhanced assumed strain method by addition of an extra displacement DOF from the central node and a reduced integration scheme are combined offering a linear varying strain field along the thickness direction to circumvent thickness locking, and an hourglass stabilization procedure is employed in order to correct the element’s rank deficiency for pinching. This element permits the modelling of three-dimensional constitutive behavior of thermoplastic prepreg with the consolidation effect, which is modelled by a viscoelastic relaxation model. An intimate contact model is employed to predict the evolution of the consolidation which permits the microstructure prediction of void presented through the prepreg. Within a hyperelastic framework, several simulation tests are launched by combining the new developed finite element and the consolidation models. The comparison with conventional shell element and experimental results shows the efficiency of the proposed solid-shell element not only dealing with the in-plan deformation and bending deformation problems, but also in analyzation of the consolidation behavior, and the degree of intimate contact provides the level of consolidation by applied process conditions, which is essential for the appearance of defects in final composite part

Full textThe soil reinforcement technique with rigid piles is an appropriate solution for most of engineering problems where the soil is compressible. The technique aims to transfer the loads of the structure to soli resistant and less-compressible soil layers. The load transfer is performed with the combination of rigid piles and an earth platform which is interposed between the rigid piles and the structure This earth platform has the advantage of transferring the load to the heads of rigid piles and minimizing the load on the compressible soil layer. Unlike deep foundations of structures, the rigid piles are not connected to the structure. The soil reinforcement technique with rigid piles is suitable for the structures like embankments, pavements, industrial areas, hydraulic treatment plants. These doctoral theses permits lo better understand the phenomena of load transfer mechanisms associated with rigid plies. Firstly, the mechanical behaviour of granular and treated soils has been investigated by laboratory tests. Then centrifuge tests were performed to understand the influence of the earth platform mechanical properties and geometric configuration of rigid piles on rigid load transfer mechanisms. Numerical approaches basin on finite element and finite difference are presented. The geometric parameters of rigid piles and mechanical characteristics of mattress distribution are investigated by a parametric study. The results of numerical modelling provide important information on the functioning mechanisms of rigid plies. The dynamic behaviour of rigid Inclusions is studied. The vertical and horizontal dynamic response of rigid piles is analyzed. A three-dimensional dynamic analysis of rigid piles is presented to understand the influence of the top and tip fixations on the dynamic behaviour of these rigid piles

Full textThis thesis illustrates a research on cell assemblies, groups of closely connected, synchronously activating neurons, which are thought to be the units of memory. After a review of the main experimental and theoretical advances in this field, and of the techniques of statistical physics and inference for the study of interacting neurons, a new method to unveil cell assemblies from neuronal data is illustrated and applied to multi-electrode recordings in the prefrontal cortex of rats during performance of a task and during the preceding and following sleep epochs. The method is based on the inference of an Ising network of effective interactions between the neurons and on the simulation of the inferred model in the presence of a global uniform drive: as the drive increases, configurations of high activity (cell assemblies) are unveiled, which activate in the data on time scales of tens of ms, in the presence of transient stimuli. The assemblies are robust with respect to noise. Comparisonof the interaction networks and of the results of the simulations across the three experimental phases reveals empirical rules for the modification of cell assemblies. The inferred model is also exploited to estimate the reactivation (replay) of the cell assemblies during sleep, important for memory consolidation. Inference and sampling of a generalized linear model show that there is not a specific order of activation of the neurons in the groups. It is finally discussed an application of descriptive statistics to the study of synaptic plasticity of neurons in vitro in an optogenetic framework
