Composite Defect Significance.

Abstract

State of the art of defect criticality assessment in structural composite laminates has been summarized and significance of other ongoing programs has been reviewed through literature survey and organization of a limited attendance symposium on the subject. A number of tests have been performed to determine the range of validity of criticality criteria for disbonds in laminated beam and plate type structures, which were developed in previous related programs. Data correlation studies have shown the usefulness of linear elastic fracture mechanics approach, methods of stress analysis based on 2-D elasticity and modified laminated plate theories as well as semi-empirical growth laws for cyclic loading for assessing growth of disbonds under transverse shear.
