Abstract The next-generation of composite structures, known as Multifunctional (MF) composites, involves combining various functions, such as structural and electrical, through multiple subsystems blended within a structural housing. The performance of MF composites can be affected by the degradation of any of these subsystems. Structural Health Monitoring Systems (SHMS) have emerged as a feasible method with which to improve the reliability of MF structures. However, the reliability of an SHMS can be affected by erroneous information from its sub-components such as transducers. Improving reliability requires a new capability to delineate failures associated with transducers and the transducer network from actual damage in the structure being monitored.
