Experimental Applications of a Case Based Reasoning Method for Structural Damage Assessment

摘要：

Some methods developed for damage identification in Structural Health Monitoring use the numerical model of the structure,others use previous experiments.The work presented in this paper presents a hybrid methodology of reasoning,combining the use of a numerical model and/or experiments in the structure with a knowledge-based reasoning scheme to evaluate if damage is present,its severity and its location.The methodology involves some elements related to vibration analysis,mathematics(Wavelets,Statistical Process Control),signal/pattern analysis/processing(Case Based Reasoning,Self Organizing Maps),smart structures and damage detection.Approaches are numerically and experimentally validated considering corrosion,mass reduction,adding masses and impact loads.Smart structures considered in this work are:an aluminium beam,two pipe sections and a portion of a wing aircraft.
