-Carbon-Fibre-Reinforced Polymers (CFRP) are now widely used in aerospace industry
+<WRAP center box 100% centeralign>
-thanks to their high strength-to-weight ratio.
+[[team:gdeliege:composite|{{:team:gdeliege:labelcomposite.png}}]]\\
-However, the numerical simulation of CFRP laminates up to failure is not trivial:
+**[[team:gdeliege:composite|Composite materials]]**
-laminates have anisotropic mechanical properties and

-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.

-The idea is to describe the laminate as
+===== Skills and competences =====
-a stack of 3D homogeneous plies separated by 2D interfaces.
-The plies are orthotropic with an elastic behaviour and brittle failure
-along the fibres
-and an elastoplastic behaviour with progressive damage in shear.
-The 2D interfaces between the plies are elastic with progressive damage.
-One interesting feature of Ladevèze and Allix's work is that the parameters
+**Languages**
-of the constitutive laws can be linked to physical quantities,
+  * French (mother tongue)
-which allows their identification with suitable experimental tests.
