Improvement of the simulation tools dedicated to composite structures subjected to crash loads
Résumé
In the framework of transport industries, vehicle design optimisation represents a key priority issue. Indeed, this is a result of the huge pressures imposed on industrialists particularly in terms of active safety. Moreover, among of all the materials used for design, some such as composite materials require special attention. It is consequently within this framework that we propose to describe in this paper the contributions which were made to the numerical simulation tools for structural analysis. The latter can involve crash type loading for example. In a first instance, certain behavioural phenomena and their integration into the computational code will be described. Secondly, some elementary validations will be presented. Finally, some applications relating to the dimensioning of panels in composites subjected to linear or point impacts will be revealed. The conclusions of these studies will enable us to show, on the one hand, a certain reliability of the developments which permit their use as design tools but also, on the other hand, to foresee the prospects of future research.
