Abstract
A four point bend setup is used in observing compressive damage initiation in a unidirectional carbon/epoxy single edge notch beam. Damage initiation is observed in 8 specimens with a camera during testing and the test is stopped when damage occurs. Post observation of the polished specimens showed a micro buckling instability at the notch tip in 5 specimens and splitting in 3. The damage initiation is modeled as an individually discretized...
