In this paper, we present a new simulation tool for process engineers. During process design phases, several aspects of machining have to be taken into account. Classical CAD/CAM suites still lack some crucial issues. The goal of the developed tool is to predict the geometric errors of machined surfaces. For classical applications of the automotive domain, form errors are mainly due to the machined part and clamping system flexibility. They are modeled thanks to the FE method. The major peculiarity of the adopted model is to apply numerous load cases. To achieve a low computational coast, we have combined the SAMCEF superelement feature and a specific code to solve the reduced system. This original scheme allows solving efficiently large industrial applications. [less ▲]

The paper presents a simulation tool designed to predict form errors of part surfaces obtained by face milling and turning processes. For these operations, the form error is often due to the flexibility of the workpiece and its supports. The finite element method is adopted to model the part geometry and to compute its deformations. Numerous load cases are required to obtain the form error so that classical resolution methods prove to be inefficient (CPU time, memory and disk space). The paper mainly focuses on the special computation scheme adopted in order to improve the resolution of such an atypical problem. [less ▲]

The synthesis of a series of poly(ethylene oxide)-b-polystyrene copolymers with different block lengths was performed by radical addition fragmentation chain transfer. These amphiphilic copolymers were tested as stabilizers for water-in-oil medium internal phase emulsion (MIPE) templating polymerization and the formation of polyMIPEs with controlled morphology. Aside from the structure of the emulsion stabilizer, several parameters susceptible to influence the size of the cavities and the interconnectivity of the porous monoliths were probed including the choice of the comonomers, treatment of the emulsion by ultrasound, the use of controlled radical polymerization method for the network formation as well as interfacial initiation. Interconnected cellular monoliths were produced. The polymerization of the ultrasonicated water-in-ethylhexylacrylate/divinylbenzene MIPE notably led to near-mesoporous open-cell material. Mechanical properties and specific surface areas of the polyMIPEs were also investigated and discussed. [less ▲]

Cet article présente une approche macro-cinématique permettant de décrire les schémas de déformation avec fissures diagonales des poutres-voile continues. On montre comment une poutre continue formée de deux travées symétriques et supportant deux charges concentrées égales peut être modélisée à partir de seulement deux degrés de liberté. Ce modèle cinématique est combiné avec une théorie cinématique à trois paramètres (3PKT) qui permet de calculer la résistance au cisaillement de poutres-voile, les réactions d’appuis à la ruine et la capacité de déformation de poutres-voile continues. Cette approche a été appliquée à quatorze essais de cisaillement issus de la littérature avec différentes hauteurs de section, différents arrangement de l’armaturage longitudinal et différentes quantités d’armaturage de cisaillement. Les résultats montrent que cette approche macro-cinématique basée sur deux degrés de liberté reproduit correctement les tendances observées dans la capacité ultime au cisaillement des spécimens.

Confronted with increasing problems of financing in health care, some question the relevance of certain interventions of high technicality. Today, the limiting factor for practitioners is not any longer situated at the technical and technological level (the survival of macro replantations is assured in 85-90%) but moves slowly and surely towards the economic level. It is true that medicine has a price and that if a technique is expensive, it should at least be justified at the human level and superior to other less expensive therapeutic options which are available. In this article, we will first focus on the long-term outcome of patients and also on the functional benefit which brings them replantation compared to patients who underwent a regularization of their stump and possibly a reconstruction enabling them to be correctly fitted with a prosthesis.
