High-Velocity Impact and Material Behavior

A method for the prediction of fracture under dynamic loading for small structures made of a 3D carbon/carbon composite is proposed. Owing to the length scale of the loading, the notion of homogenised material is meaningless and our choice then is to model, identify and compute the material at an intermediate or mesoscale (fibre-strands/matrix-blocks). The idea here is that, because of the small size of the meso scale, the previous description of the damage mechanisms should be valid even for high-rate loading. This work is focused on the application of this approach to the case of plate/plate impact by making use of a simplified analysis.
