| Résumé : |
In this paper, the LMS Samtech Samcef finite element code is used to assess the damage tolerance of composite structures. Delamination (ply separation), which is one of the most dangerous and predominant failure modes in daminated composites, is addressed. Two methods are used. The first one is based on a pure fracture mechanics approach, namely VCE (virtual crack extension), while the second method relies on cohesive elements and on continuum damage mechanics. These methods are implemented in the commercial version of LMS Samtech Samcef. This means that, besides the commercial FE solver, no additional (and costly) plug-ins providing such capabilities are required to solve the problem. Another advantage is that the user does not have to implement academic methods or models that may be described in the literature. Even if the openness of LMS Samtech Samcef is available via material user routines, a native implementation in a commercial software program always provides a more reliable solution. |
