Résumé

This study presents an experimental protocol for the characterization of the strain rate effects on the nonlinear behavior of an organic matrix composite. This protocol is based on the development of a displacement interrupted tensile test device adapted to servo-hydraulic jacks. The protocol allows for the performance of incremental cyclic tests for intermediate dynamic loading rates thanks to the device. Such combination allows for the evaluation of the macroscopic damage variable, the irreversible strain and the reversible phase after nonlinear loading. It also allows for the analysis of damage mechanisms such as cracks and delamination after cyclic dynamic loadings.
