Synopsis:

Technologies need to be developed to monitor ship hull and structural integrity as U.S Navy and maritime industry designs increasingly rely on lightweight materials such as composites and aluminum for ship structures in order to meet future high speed/high performance goals. Wave loadings at high speeds result in pressure fields that challenge local and global structural integrity to a degree not supported by traditional Navy or commercial design approaches. There is little generic experience related to maintaining structural performance of lightweight high-speed ships. This is especially true as they age. Currently, there are several US Navy research and development programs that contain the development of structural monitoring system for ship hull and structural components. Examples of such R&D efforts will be given. Previous and current activities as well as required technologies for health monitoring of ship structures will be discussed. The continued advancement of pertinent technologies will ultimately enable a comprehensive structural health monitoring system that includes diagnostic methods and prognostic capabilities to proactively manage future ship hull and structures.

Bio:

Dr. Liming Salvino received her Ph. D. in condensed matter and computational physics from The American University, Washington DC in 1989. After graduation, she became a postdoctoral fellow and research associate at University of Maryland. Since 1996, she has been employed by NSWC, Carderock Division. Dr. Salvino has done research work in many areas of physics, applied mathematics and engineering. Most recently, she has been involved in structural health monitoring R&D (research and development) activities for the US Navy.
