LAGAMINE is a code of finite elements initially developed for the digital modelling of large deformations, mechanical problems and contact problems.

T

he code was developed in two different fields: (i) the behaviour of metals and (ii) geomechanics. The research carried out by the two teams have the same digital code allowed for a cross-fertilisation of both groups. The researchers’ ongoing work throughout the world as well as in universities and even industry has maintained this code at the cutting edge of technology and research.

 

Description

LAGAMINE was initially developed to model the formation of metals (especially rolling) for the ARBED’s research group: LAGAMINE is actually an anagram of LAMINAGE (the French word for rolling).

 

The Metal research team is managed by AM Habraken, alongside Prof Cescotto (retired in 2012), who succeeded professor Duchêne. It is a digital team with strong experimental implications with materials and structures (Laboratoire de Mécanique M&S). Its main focus is on the behaviour of materials (steel, Ti, Al, Ni, metals and coatings). Its activities are the development and identifying laws of thermomechanics and metalworking within a multi-scalar approach.

 

These rheological models, implemented in LAGAMINE, allow to predict the damages and rupture along the process of formation, as well as the static and specific fatigue load. Simulations can be extended to the modelling of processes such as deep-drawing, straightening, cold rolling, continuous casting, incremental forming, vertical lancer combined, superplastic forming or former microforming. In these simulations, the shaping of metal, of new elements such as solid-shell elements or adapted darning strategies have also been developed within LAGAMINE.

 

Since the 1980s, digital developments in geomechanics have been supported by successive doctoral research conducted under the supervision of professors Robert Charlier and Frédéric Collin (since 2011). The main subject of the research is linked to the geomechanical environment, that needs Chemo-Thermo-hydro-mechanic coupled models.

 

These digital works are two-sided: on one hand, the strongly coupled laws of behaviour are implemented in the code using elasto-plastic, elastoviscoplastic settings or a multi-scalar approach, and on the other, completely coupled with finite elements dedicated to the modelling of multiphase or multiphysical problems.

 

All these developments have been implemented within LAGAMINE, which thus constitutes a unique digital tool for modelling underground storage of nuclear waste, geothermal reservoirs, oil and gas reservoirs, etc.

 

The community of users

LAGAMINE is currently being used by the University of Liège researchers without restriction of use. All engineering students have access to a free licence, for the whole length of their school year. The software is currently being used by CRISMAT (Caen, France), the University of Concepcion (Chile), ARCELOR MITTAL (Maizières-les Metz and Esch-sur-Alzette centres).
