Abstract
A measure of correlation between mode shapes is introduced. This measu re is a modification of the standard Modal Assurance Criterion (MAC). The new form, called the Modal Correlation Coefficient (MCC), is more sensitive to the existence of kinks in mode shapes. Ils advantages are realized in diagnostic and structural health monitoring applications.
