Abstract

The use of composite materials has vastly increased in recent years. Great interest is therefore developed in the damage detection of composites using non-destructive test methods. Several approaches have been applied to obtain information about the existence, location and growth of the faults. The main goal in this paper is to use the vibration response of a composite plate to detect and localize delamination defect based on the frequency response and modal analysis. The features extracted are used as the input data in an artificial intelligence scheme to identify the severity of the damages. Experiments are then conducted to validate the developed model.
