Abstract

A procedure for the prediction of the elastic properties and failure behavior of 2D and 3D textile-reinforced composites is presented in this paper. Homogenization techniques based on energetical approaches are performed on multi-scale sub-elements in order to distinguish elastic from fracture behaviors. Scale details range from the filament to the yarn and the unit-cell. The reliability of our procedure is proved in the case of woven and SD-braided composites and the sensitivity to geometrical parameters are simulated. 1 Introduction The potential of 2D and 3D textile-reinforced composites is high but the challenges involved in predicting their mechan
