This report is an updated version of the previous literature review report (LA-13070-MS) entitled “Damage Identification and Health Monitoring of Structural and Mechanical Systems from Changes in Their Vibration Characteristics: A Literature Review” by S.W. Doebling, C.R. Farrar, M.B. Prime, and D.W. Shevitz. This report contains new technical developments published between 1996 and 2001 in the discipline of structural health monitoring. The reviewed articles first are organized following the statistical pattern recognition paradigm reported in Farrar and Doebling (1999). This paradigm can be described as a four-part process: (1) Operational Evaluation, (2) Data Acquisition, Fusion, and Cleansing, (3) Feature Extraction and Information Condensation, and (4) Statistical Model Development for Feature Discrimination. The reviewed articles are then categorized by type of applications, which include beams, truss, plates, bridges, aerospace structures, and composite structures. Other useful resources for the structural health monitoring (SHM) community such as SHM-related projects, web sites, conferences, and technical journals are listed. This report concludes by summarizing the current state of the art of SHM technologies and by identifying future research areas necessary to advance the SHM field.
