Research abstract
A NOVEL APPROACH TO ON-LINE MONITORING OF DEGRADATION OF COMPOSITE MATERIAL WILL BE INVESTIGATED. THIS APPROACH UTILIZES THE DYNAMIC RESPONSE CHARACTERISTIC OF THE COMPOSITE COMPONENTS AND A PATTERN-RECOGNITION METHOD. THE DYNAMIC RESPONSES OF A PERFECT AND A DEGRADED COMPONENT CAN BE SIMULATED THROUGH A FINITE-ELEMENT ANALYSIS. THE RESULTSCAN BE USED IN A TRAINING-LEARNING EXERCISE THROUGH AN EXPERT SYSTEM TO CLASSIFY THE DEGRADATION STATUS OF OTHER SIMILAR COMPONENTS. THIS APPROACH WILL ALLOW AN EFFICIENT, QUALITATIVE ASSESSMENT OF THE WELL-BEING OF THE COMPONENT. A NOVEL APPROACH TO ON-LINE MONITORING OF DEGRADATION OF COMPOSITE MATERIAL WILL BE INVESTIGATED.
