摘要：
The influence of transverse damage on compressive strength in fiber direction for carbon fiber reinforced epoxy materials is investigated by an experimental approach. Several experimental methods are proposed. The first study focuses on tubular samples. Theses samples are damaged by torsional and cyclic load and next submitted to compressive load. Results show that the transverse damage affects the compressive strength. Yet the stiffness is not modified. A model is then proposed with these results. The second study focuses on plates with stress concentrations. A non-local criterion is introduced in order to take the stress concentration into account. Results are in good agreement with the model identified on tubes.
