Étude de l’origine physique de la non linéarité élastique en traction et compression des unidirectionnels à fibres continues de carbone
Abstract
Unidirectional continuous carbon fibre composite laminates exhibit non-linear elastic behaviour, characterised by stiffening under tension and softening under compression. It has been shown, for a small range of deformation, that this non-linearity is due to the ply material and that the contribution of the ply-inner fibre waviness is negligible. However, the study was not carried out over the entire deformation range of the laminates, i.e. up to failure. This is the purpose of this paper, which uses experimental results from four-point bending tests and a numerical model of this test. The evolution of the position of the neutral fibre with loading is taken as an indicator of the non-linear behaviour. The introduction of the four (experimentally determined) parameters characterising the non-linearity into the numerical model allows to highlight the obvious contribution of the material to the non-linearity at the beginning of the loading. At the same time, the geometric contribution of fibre waviness is determined using a non-local numerical model. Its contribution to the non-linearity is evaluated.
