Magnetostrictive sensor (MsS) technology is an emerging method to cost-effectively inspect large structures using
ultrasonic guided waves. Recent research focuses on applications demanding small, robust sensors. To adapt to these
applications, SwRI has extended MsS capabilities to generating bulk and surface wave modes. Bulk wave applications
are demonstrated on a laboratory specimen with artificial damage. Surface wave inspections are demonstrated to monitor
large areas of a thick-walled containment type structure.
