Postition for Post-Doctoral Researcher (Maître-assistant associé(e)) "Multi-scale modeling of heterogeneous composite materials"
General description
Increasing interest in using of textile reinforced composites for industrial applications leads to continuing demand on highly robust methods for the analysis of lightweight materials such as composites. Nevertheless, the inherent heterogeneity of such materials has been a main issue in the numerical modeling for the structural analysis and design. Therefore, the understanding of the mechanical behavior of composite materials at the different material scales, i.e. fiber scale, yarn scale and product scale, is necessary and an important step in the development of numerical design tools. This project focuses on the implementation of improved computational techniques based on a multi-scale approach for 2D and 3D textile reinforced composite materials.
Objectives
The general objective of the project is to develop a numerical simulation tool for efficient and robust multi-scale modeling of the mechanical behavior of composites considering the following key challenges. The first one is the predicting of non-linear response and failure at different scales. The second one is incorporating the variability of the mechanical properties and of the material microstructure which can be induced from manufacturing defects (fiber misalignment, voids, etc.) or from the inherent scattering of constituent material properties such as natural fiber reinforcement. The identification and quantification of defects will be obtained from X-ray computed tomography data. The post-doc will be involved in both theoretical and experimental investigations.
