- | 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: |
- | However, the numerical simulation of CFRP laminates up to failure is not trivial: | + | **[[team:gdeliege: |
- | 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) | + | <WRAP third column> |
- | that are not easily described at a macroscopic level. | + | <WRAP center box 150 centeralign> |

- | 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|{{: |
