The formulation of macroscopic constitutive laws for the behaviour of masonry is a complex task, due to its strongly heterogeneous microstructure which influences its overall mechanical behaviour. This has triggered in the past decade the formulation of homogenisation methods, both for linear and damaging behaviours, and for in and out-of-plane loading conditions. This contribution deals with two-scale computational framework, in which the material behaviour of a structural masonry shell is sampled by resorting to computational homogenisation applied on a microstructural description of masonry constituents. The structural damaging behaviour is modelled by incorporating localising hinges in a coarse scale thin shell description. The appearance, the orientation and the softening mechanical response of these hinges are directly deduced from the computational homogenisation scheme. This procedure allows incorporating naturally the anisotropic damaging effects of the masonry material degradation. The contribution will illustrate the two-scale results by comparing them to full fine scale models. [less ▲]

This paper presents a multi-scale framework for the failure of periodic quasi-brittle thin planar shells. The failure behavior of textured or periodic heterogeneous materials is strongly influenced by their mesostructure. Their periodicity and the quasi-brittle nature of their constituents result in complex behaviors such as damage-induced anisotropy properties with localization of damage, which are difficult to model by means of macroscopic closed-form constitutive laws. A computational homogenization procedure is used for the in-plane and out-of-plane behavior of such planar shells, and is combined with an acoustic tensor-based failure detection adapted to shell kinematics to detect the structural-scale failure. Based on an assumption of single period failure, the localization of damage at the structural scale is represented by means of mesostructurally informed embedded strong discontinuities incorporated in the macroscopic shell description. A new enhanced scale transition is outlined for shell failure, based on an approximate energy consistency argument to objectively upscale the energy dissipation. The corresponding multi-scale framework results are compared with direct fine-scale modeling results used as a reference for the case of masonry, showing good agreement in terms of the load-bearing capacity, of failure mechanisms and of associated energy dissipation. © 2010 John Wiley & Sons, Ltd.

In this report written for the Utrecht Congress of the International Academy of International Law, I review the position of same sex couples, be they married or bound by a partnership, under Belgian law. Specific attention is devoted to the treatment under Belgian law of cross-border couples (couples with other nationalities than Belgian nationality, or whose habitual residence is or was established outside Belgium). Among the questions studied two stand out : first the question of who can validly conclude a same sex marriage or enter into a partnership in Belgium and second the issue of the recognition in Belgium of same sex marriages or partnerships concluded abroad.

Les couples et les familles avec partenaires et parents LGBT (lesbiens, gays, bisexuels, transgenres) sont souvent passés sous silence dans l’approche systémique. Ce silence trouve ses racines dans l’hétérocentrisme qui a influencé la définition de couple, de famille et de relations familiales ainsi que de leur « normalité » vs « pathologie ». Qu’on soit chercheur ou clinicien, il est intéressant de prendre en considération l’impact de l’homophobie, de l’hétérosexisme, de l’hétéronormativité dans la vie quotidienne de ces couples, de ces familles et de leurs enfants. En particulier dans la consultation clinique, il semble important d’en évaluer leur degré de stress, d’ambiguïté relationnelle, d’homonégativité intériorisée ainsi que de support social. Nous réfléchirons aussi sur les atouts et les limites des modèles majeurs de thérapie de couple et de famille dans le travail thérapeutique ainsi que sur la nécessité d’envisager des pistes dans la formation du futur thérapeute sur les questions LGBT. Formation qui pourrait être basée sur le modèle de la diversité comme modèle inclusif des différences familiales et relationnelles contemporaines. [less ▲]

A primitive equation model and a statistical predictor are coupled by data assimilation in order to combine the strength of both approaches. In this work, the system of two-way nested models centred in the Ligurian Sea and the satellite-based ocean forecasting (SOFT) system predicting the sea surface temperature (SST) are used. The data assimilation scheme is a simplified reduced order Kalman filter based on a constant error space. The assimilation of predicted SST improves the forecast of the hydrodynamic model compared to the forecast obtained by assimilating past SST observations used by the statistical predictor. This study shows that the SST of the SOFT predictor can be used to correct atmospheric heat fluxes. Traditionally this is done by relaxing the model SST towards the climatological SST. Therefore, the assimilation of SOFT SST and climatological SST are also compared. (c) 2006 Elsevier Ltd. All rights reserved. [less ▲]
