Abstract:

Crack is one of the most common damages in composite laminated plates,and it is the chief factor of causing failures.When there is a crack in composite laminated plates,the inner energy distribution changes,and will cause significant changes in the dynamic behaviors.Therefore,the diagnostic rules of crack failures can be developed by studying the dynamic behaviors of composite laminated plates under healthy and damaged conditions respectively.

Key words: composite material, laminated plate, crack diagnosis, dynamic behavior
