An enhanced Bayesian approach for damage identification utilizing prior knowledge from refined elemental modal strain energy ratios

Abstract This study proposes a novel Bayesian damage identification method that uses an Improved Elemental Modal Strain Energy Ratio (IEMSER) to guide a sparse prior distribution. Measured frequencies and mode shapes develop the IEMSER indicator for preliminary damage assessment, forming the basis f...
