Standard numerical simulations for optimization or inverse identification of welding processes remain costly and difficult due to their multi-parametric aspect and inherent complexity. The aim of this paper is to propose a non-intrusive strategy for building computational vademecums dedicated to real-time simulations of nonlinear thermo-mechanical problems. There is in essence, a set of precomp...

Giant Unilamellar Vesicles (GUVs) consisting in self-closed lipid bilayers of 0.5-100 µm diameter are considered as oversimplified models of cells because of their biological membrane and micrometric size while Large Unilamellar Vesicles (LUVs) of 100-500 nm diameter have applications in drug delivery. To improve structural and mechanical properties of these vesicles, we have developed two cate...

Design of deformation (thermo-mechanical) processes to achieve desired structural response will be addressed. Plastic deformation is assumed to be accommodated through crystallographic slip and reorientation of crystals. Conventional methodologies towards polycrystal plasticity use an aggregate of single crystals and this choice of the aggregate affects the response of the polycrystal. In order...

The storage of high level radioactive waste is still an unresolved problem of the nuclear industry, being geological disposal the most favoured option and, naturally, the one requiring the strongest geo-mechanical input. Most conceptual designs for the deep geological disposal of nuclear waste envisage placing the canisters containing the waste in horizontal drifts or vertical boreholes. The em...

Developing medium-Mn steels (MMnS) demands a better understanding of the microstructure evolution during thermo-mechanical treatments (TMTs). This study demonstrates relationship among processing, microstructure, and mechanical properties warm-rolled steel containing 1.5 wt. % Cu Ni. After short-time warm rolling (WR) in an intercritical temperature range, significant quantity (40.6 vol.%) aust...

The aim of this work was to investigate the effect hot deformation on aging behavior precipitation-hardenable aluminum alloy AA7075 within a novel thermo-mechanical forming process, in order gain insight into its precipitation kinetics. For purpose, material formed at 420 °C after undergoing solution treatment different strain levels ranging from 2% 10% obtain dislocation densities. After defor...

A computational thermo-mechanical model has been developed to simulate the continuous casting of shaped sections, such as used for thin steel slabs. A general form of the transient heat equation including latent-heat from phase transformations such as solidification and other temperature-dependent properties is solved numerically for the temperature field history. The resulting thermal stresses...
