PARTICULAR BEHAVIOUR OF CERTAIN COMPOSITES RELATED TO BASIC DAMAGE DETECTION TECHNIQUES

Abstract

This paper deals with dynamic damage detection involved on composites based st ructures analysis. It contains a briefly presentation of some particular and inadequate aspects of a certain composites regarding their ordinary behaviour under dynamic loads during the exploitation time and the implication on the damage monitoring process. The particularities of demotion processes and the selectiveness of damages initiation/developing into the basic array materials can lead to inappropriate evolution during exploitation for some structural systems subjected to external dynamic loads. In these cases the damage process monitoring can be significant affected by missing of essential information related to qualitative and quantitative changing of the dynamic parameters. The previous hypothesis must be added by taking into account the serviceable and the disposable means used for system status evaluation
