The risk of resource depletion for future generations of humanity is often cited as an important issue. The choice of impact categories and characterization models for resource extraction in LCA is no more precise than other impact categories and models. This means that more discussion is needed on the use of resources. In this article, the potenti...
Borate is an essential material to numerous industries and even to individual countries’ economies, defense, and politics. Almost all industries need borates for production, and almost everybody needs their products. Borate is a compound that contains or supplies boric oxide (B2O3). Among the minerals that contain boric oxide, there are only four m...
A polycrystalline plasticity model, which incorporates the contribution of deformation twinning, is proposed. For this purpose, each material point is treated as a composite material consisting of a parent constituent and multiple twin variants. In the constitutive equations, the twin volume fractions and their spatial gradients are treated as exte...
Although there are a lot of studies in literature related to the life cycle assessment (LCA) of mining, there are only a few studies done on the boron mining industry. This paper presents an LCA of the boron mining industry including the extraction, beneficiation, and refinement processes. The main purpose is to identify and compare the environment...
This article synthesises the return of experience of performing a product variety analysis for a (supplier in the automotive sector) that haven’t had yet a product variety management strategy. This paper is part of a multi-year research project on the design of reconfigurable production systems. The contribution is (i) to present at a glance the de...
In this paper, hexagonal closed packed (HCP) sheet metal ductility for a viscoplastic material is analyzed by using a linear perturbation technique. It can be used for the analysis of local-ized necking. This technique is used to perturbate the material behavior in a rate dependent formulation by superimposing a perturbation to the basic flow which...
L'économie d'énergie est devenue un véritable enjeu dans la gestion des procédés et a conduit à l'analyse de la consommation d’énergie des machines de forgeage, et ce à des fins d'optimisation. Dans ses travaux, on s’intéresse à la quantité et à la façon dont l'énergie est dissipée par une presse à vis lors d’opérations de forgeage de produits mass...
This paper presents a decision tool for the optimisation of wind turbine technical parameters, using a multi-physical model of the power system. This includes a multi-physical modelling of aerodynamical, mechanical and electro-mechanical system behaviours. The aerodynamics is based on a blade element momentum model. A mass model of wind turbines co...
In this study, a model formulated at the ply scale was considered to describe the mechanical behaviour of an acrylic-thermoplastic-matrix and glass-fibre-reinforced laminated composite under monotonic tensile and fatigue loadings within a temperature range of − 20 ◦ C to +60 ◦ C. This study showed that the temperature dependency of the composite tr...
A promising advance of bioengineering consists in the development of micro-nanoparticles as drug delivery vehicles injected intravenously or intraarterialy for targeted treatment. Pro cient functioning of drug carries is conditioned by a reliable prediction of pharma- cokinetics in human as well as their dynamical behavior once injected in blood st...
