-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 +</WRAP>

-This model is inspired by the meso-model +</WRAP>

-The idea is to describe the laminate as a stack of 3D orthotropic plies separated by 2D interfaces. +<WRAP group> 
-In a direction parallel to the fibres, +<WRAP third column> 
-the plies are elastic and subject to brittle fracture; +<WRAP center box 100% centeralign> 
-in shear, an elastoplastic behaviour is assumed and progressive damage is introduced. +[[team:gdeliege:mems|{{:team:gdeliege:labelmems.png}}]]\\ 
-The 2D interfaces between the plies are elastic with progressive damage. +**[[team:gdeliege:mems|Microelectromechanical systems]]**

-One interesting feature of Ladevèze and Allix's work is that most parameters of the constitutive laws +===== Education and training =====
-can be linked to physical quantities. +
-Therefore, these parameters can be identified with suitable experimental tests.+
