Study on Damage Identification of Simply Supported-Beam Based on Modal Strain Energy Method

Abstract:

In present study, ANSYS finite element method was utilized to analyze the modal of simply supported beam and then the study on damage identification was performed based on modal strain energy method. The comparative analysis of results obtained by modal strain energy changes rate method and modal strain energy index demonstrates that modal strain energy index is an effective damage identification parameter.
