ORBi Open Repository and Bibliography (297.212 recursos)

In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

  1. Stochastic multiscale modeling of MEMS stiction failure

    Hoang Truong, Vinh
    In the context of microelectromechanical systems, due to their reduced size, the surface phenomena, e.g. adhesion contact, play an important role in the reliability of the devices. Indeed, the adhesive forces, e.g. capillary and van der Waal forces, can lead to the stiction failure for which the two contacting surfaces can accidentally be stuck together permanently. This is a common failure of MEMS. Because of the comparability between the roughness of the contacting surfaces and the ranges of adhesive stress, the interaction area can be much smaller than the apparent one. Since the contact zone is reduced and becomes comparable with the characteristic length scale of the...

  4. Effect of orthopedic implants on long bone properties : a combined experimental and numerical approach

    Laurent, Cédric; Verwaerde, Jolante; Böhme, Béatrice; Ponthot, Jean-Philippe; Balligand, Marc
    Long bone fracture constitutes a common reason for medical consultation within veterinary orthopedic services (Miller et al. 1998; Kumar et al. 2007). Canine bone fracture repair differs from the human case in the sense that (1) the physiological characteristics and morphology of the injured bones in animals vary considerably (Palierne et al. 2006), (2) the animal is not able to limit its activity during the post-operative period, leading to premature overloading, and (3) the surgeon is confronted to cost limitations concerning orthopedic material. There is a lack of studies assessing the effect of different treatment types on the biomechanical properties...

  5. Nonlinear analysis of compliant deployable structures: modelling, simulation and experimental validation

    Dewalque, Florence
    Compliant mechanisms are flexible components which can store elastic energy when deformed and then passively release it to produce a motion. Their scope of applications encompasses various domains from robotic orthoses to microscopes and grippers. In this work, the developments focus on compliant mechanisms called tape springs used in deployable space structures. Tape springs, due to their autonomous deployment capacity from a compact folded configuration, their high stiffness in the deployed equilibrium state and their simplicity of integration, represent efficient alternatives to common motorised hinges for space applications. Thus, they are currently used to deploy appendices on satellites such as solar...

  7. Damage Detection in Structures Based on Principal Component Analysis of Forced Harmonic Responses

    Golinval, Jean-Claude
    Peer reviewed

  8. Development of non-linear Electro-Thermo-Mechanical Discontinuous Galerkin formulations

    Homsi, Lina
    A coupled Electro-Thermo-Mechanical Discontinuous Galerkin (DG) method is developed considering the non-linear interactions of electrical, thermal, and mechanical fields. The numerical properties of the DG are demonstrated, such as uniqueness, consistency, stability and the optimal convergence rate. The framework is applied to simulate the response of smart composite materials, where the shape memory effect is triggered by the Joule effect.
