-Carbon-Fibre-Reinforced Polymers (CFRP) are now widely used in aerospace industry

-thanks to their high strength-to-weight ratio.
+<WRAP third column>
-However, the numerical simulation of CFRP laminates up to failure is not trivial:

-My objective was to implement a material model for composite plies with woven fibre
+===== Skills and competences =====
-reinforcement in Metafor.
-This model is inspired by the meso-model
-proposed by P. Ladevèze and O. Allix [1-2] for unidirectional
-composites as well as the 2D model for woven composites proposed by C. Hochard [3].
-The idea is to describe the laminate as a stack of 3D orthotropic plies separated by 2D interfaces.
+**Languages**
-In a direction parallel to the fibres,
+  * French (mother tongue)
-the plies are elastic and subject to brittle fracture;
+  * English (advanced)
-in shear, an elastoplastic behaviour is assumed and progressive damage is introduced.
+  * Dutch (advanced)
-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
+**IT**
-can be linked to physical quantities.
+  * software development : knowledge of C/C++, Python, Matlab, parallel programming tools (MPI), version control tools (Subversion)
-Therefore, these parameters can be identified with suitable experimental tests.
+  * finite element software (university code ; Samcef ; marginal use of MagNet, ANSYS, LS-DYNA)
+  * Linux system management
