When a laminated composite is subjected to compressive loads a delaminated region may buckle. This causes high interlaminar stresses at the delamination front and the delamination may grow. In this study, the effect of multiple delaminations on the postbuckling behavior of laminated rectangular plates is studied experimentally. In the experimental study extensive strain gauging is involved to obtain a thorough investigation of the behavior of the distribution of the surface strains on the plate. Results of the experimental investigation are compared with the theory developed by Chai (Chai, C B., The effect of geometry and prescribed delamination on the postbuckling behaviour of laminated carbon-fiber reinforcing plastic panels.
