Abstract

This research activity report is mainly based on the last 14 years work for understanding and modeling the nonlinear mechanical behavior of aeronautical composite materials. Being initiated during my PhD, this work is an extent of it, oriented to the analysis of damage phenomena (initiation and propagation) under static or rapid dynamic loadings for a broad range of composite materials such as short fibers composites, unidirectional composites, and woven composites, with thermoplastic or thermoset matrix. The most relevant developed material models are presented in the first part of this work, as well as a proposed identification methodology and methods that can be used to demonstrate the models' robustness. The second and last part of this work gives a general overview of industrial applications of these developments, in three fields: - forecast of defects during and after drilling process, - interaction between drillings defects and hammering behavior of bolted joints, - forecast of defects during and after low velocity impacts.
