Analytical and numerical simulation of the behavior of 2.5D braided interlock composite tubes under crush loading.

Résumé

This article deals with the experiment and numerical simulation of the crash of compositetubes made of 2,5D-braided composite. In a first part, 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, we describe the bi-phase material model which hasbeen developed. It is based on Drozdov’s modelling for thermoplastic matrix and on thekinking modelling for fibers. In a last part, we present the experiment and numericalsimulations correlations and we will conclude more particularly about the good predictingthe value of energy absorption.
