| Popis: | International audience; This article deals with the experiment and numerical simulation of the crash ofcomposite tubes made of 2,5D-braided composite. First we present the materialcharacterization at different strain rates as well as the results of tubes which have been testedin a drop-weight tower. In a second part, simple analytical tools results are described andtheir results are compared with experimental ones. In a third part, we describe the bi-phasematerial model which has been developed. It is based on Drozdov’s modelling forthermoplastic matrix and on the kinking modelling for fibers. Finally we present theexperiment and numerical simulations correlations and we will conclude more particularlyabout the good predicting the value of energy absorption. |
