A numerical study on compressive behavior of composite plates with multiple circular delaminations considering delamination propagation

The compressive behavior of multiply delaminated composite plates was numerically evaluated considering both structural instability and delamination growth in order to clarify the reason for the significant reduction in the compressive strength of composite laminates that results from an impact. Embedded circular delaminations were placed at regular intervals in the thickness direction at the plate center. A three-dimensional block element was...
