An innovative procedure for characterising a coupled elastoplastic damage model of behaviour using the Virtual Fields Method

Delphine Notta-Cuvier, Bertrand Langrand, Franck Lauro, Eric Markiewicz

The characterisation of material behaviour models can be challenging, especially when dealing with strongly non-linear constitutive laws. Classical procedures are restricted to the treatment of homogeneous mechanical fields. They can therefore not be applied after strain localisation and behaviour…

Smoothed finite element method implemented in a resultant eight-node solid-shell element for geometrical linear analysis

Xavier J-G Elie-Dit-Cosaque, Augustin Gakwaya, Hakim Naceur

A smoothed finite element method formulation for the resultant eight-node solid-shell element is presented in this paper for geometrical linear analysis. The smoothing process is successfully performed on the element mid-surface to deal with the membrane and bending effects of the stiffness matrix…

Human Reliability Assessment under Uncertainty – Towards a Formal Method

Subeer Rangra, Mohamed Sallak, Walter Schön, Frédéric Vanderhaegen

Humans are and will remain one of the critical constituents of a technological system. The study of human factors is a broad domain with equally varying applications. Furthermore, with the advent of new technologies in safety-critical systems there is always a need to ensure system safety and…

Effects of robotic gait rehabilitation on biomechanical parameters in the chronic hemiplegic patients, Effets de la rééducation robotisée à la marche sur les paramètres biomécaniques de la marche chez des patients hémiplégiques chroniques

Laura Wallard, Gilles Dietrich, Yves Kerlirzin, Jonathan Bredin

Hemiplegia is a more or less complete loss of hemibody voluntary motricity following a brain injury, usually resulting in alterations of the locomotor system with persistent disorders of movement and posture. We were interested in studying the gait pattern called "stiff knee gait" with…, L’hémiplégie est une perte plus ou moins complète de la motricité volontaire d’un hémicorps suite à une lésion cérébrale, entraînant généralement des altérations de l’appareil locomoteur avec des troubles persistants du mouvement et de la posture. Nous nous sommes intéressés, pour cette étude, au…

Axisymmetric modeling of the thermal cooling, including radiation, of a circular glass disk

Norbert Siedow, Dominique Lochegnies, Fabien Béchet, Philippe Moreau, Hiroshi Wakatsuki, Nobuhiro Inoue

Achieving correct tempering in thin glass is very important to prevent undesired stress and breakage. Computer simulation can elucidate and control the tempering process. For semitransparent materials like glass, heat transfer by thermal radiation is substantial; for thick glass, it may dominate…

Revenue management for rail container transportation

Ioana Bilegan, Luce Brotcorne, Dominique Feillet, Yezekael Hayel

In this paper, we consider the revenue maximization problem of a rail freight transportation company or an intermodal marketing company selling freight transportation services. We propose a revenue management (RM) policy to dynamically accept transportation requests or reject them in favor of some…

Development of CBCT-based prostate setup correction strategies and impact of rectal distension

Christine Boydev, Abdelmalik Taleb-Ahmed, Foued Derraz, Laurent Peyrodie, Jean-Philippe Thiran, David Pasquier

Background: Cone-beam computed tomography (CBCT) image-guided radiotherapy (IGRT) systems are widely used tools to verify and correct the target position before each fraction, allowing to maximize treatment accuracy and precision. In this study, we evaluate automatic three-dimensional intensity-…

Experimental characterization and macro-modeling of mechanical strength of multi-sheets and multi-materials spot welds under pure and mixed modes I and II

Rim Chtourou, Grégory Haugou, Nicolas Leconte, Bassem Zouari, Fahmi Chaari, Eric Markiewicz

Resistance Spot Welding (RSW) of multiple sheets with multiple materials are increasingly realized in the automotive industry. The mechanical strength of such new generation of spot welded assemblies is not that much dealt with. This is true in particular for experiments dedicated to investigate…
