The possibility of improving the performance of nondestructive damage detection via combining the predictions of more than one damage theory is explored in this paper. To demonstrate the approach, the combination of two prominent approaches to damage detection is exploited: namely, the approach that utilizes the modal strain energy distributions and the one that utilizes the compliance distributions. The basic elements of the approaches are summarized. The performance of each methodology is evaluated using the data generated in a space structure. Both static and modal displacement measurements are utilized to increase the number of damage prediction sets. Three logical rules for combining the theories are proposed and the performances of these rules are compared with the performance of the individual theories.
