-==== Composite materials ====+===== Education and training =====
-Carbon-Fibre-Reinforced Polymers (CFRP) are now widely used in aerospace industry +**M.Sc., 1997 Physics Engineering, Université de Liège, Belgium** \\ 
-thanks to their high strength-to-weight ratio+Graduate Thesis title: //Raffinement adaptatif de types h et p pour le calcul des champs électromagnétiques.// \\ 
-However, the numerical simulation of CFRP laminates up to failure is not trivial: +SupervisorProf. Willy Legros.\\
-laminates have anisotropic mechanical properties and +
-laminate damage results from a combination of microscopic mechanisms +
-(fibre brittle failure, fibre-matrix debonding, matrix ductile failure and delamination) +
-that are not easily described at a macroscopic level.+
-My objective was to implement a material model for composite plies with woven fibre +**Ph.D., 2003 - Electrotechnics, Katholieke Universiteit Leuven, Belgium** \\ 
-reinforcement in Metafor+Title: //Flexible Implementation of the Finite Element Method Applied to 3D Coupled Problems Considering Convective Effects.// \\ 
-This model is inspired by the meso-model +Supervisors: ProfKay Hameyer, ProfStefan Vandewalle.
-proposed by PLadevèze and O. Allix [1-2] for unidirectional +
-composites as well as the 2D model for woven composites proposed by CHochard [3].+
-The idea is to describe the laminate as a stack of 3D orthotropic plies separated by 2D interfaces. +===== Research activities =====
-In a direction parallel to the fibres, +
-the plies are elastic and subject to brittle fracture; +
-in shear, an elastoplastic behaviour is assumed and progressive damage is introduced. +
-The 2D interfaces between the plies are elastic with progressive damage. +
-Practical information on the +
-[[doc:user:elements:volumes:ortho_hypo_materials|orthotropic materials]] +
-and +
-[[doc:user:elements:volumes:ortho_continuousdamage|damage evolution laws]] +
-is available on the Metafor web page. +
- +
-One interesting feature of Ladevèze and Allix's work is that most parameters of the constitutive laws +
-can be linked to physical quantities. +
-Therefore, these parameters can be identified with suitable experimental tests.+
