Cet article présente un élément de coque bilinéaire enrichi, adapté à la modélisationdes tôles soudées par points de soudure électrique, et implémenté sous Abaqus. L’élément debase est un élément de Simo-Rifaï en petits déplacements et en élasticité linéaire. Lamodélisation proposée des points de soudure s’inspire des méthodes de modélisationd’incl...
peer reviewed / This paper describes numerical modelling of the fire behaviour of two-way reinforced concrete slabs using a special purpose non-linear finite-element program, SAFIR. Several two-way reinforced concrete and composite steel-concrete slabs are tested under exposure to the ISO standard fire in order to validate the shell finite element ...

In the preceding companion paper, a more advanced theory for the geometrically nonlinear finite element(FE) analysis of the shell structures under eccentric follower loads has been carefully established. It is expected that the derived formulation can be applied realistically to wide range of practical problems. As an important application of the p...

An advanced numerical formulation for the geometrically nonlinear finite element analysis of the shell structures under nonconservative loads is proposed in the present paper. The nonconservative follower loads are efficiently implemented by the load correction stiffness matrix(LCSM). The implications and assumptions adopted to derive LCSM are thor...
This thesis is a summary of my research works at the MSM department of the University of Liège since 1989. These research works are devoted to the numerical simulation of the three-dimensional sheet metal forming processes by the finite element method. Several research areas, including the finite element modelling, the time-integration technique of...
