Palo Alto Colloquia
The Palo Alto Colloquia are a long-standing tradition of public outreach that deliver information about aerospace research and development to the local community. All presentations are given on Thursdays at 4:15 p.m. in the Lockheed Martin ATC Auditorium in Building 202 and last about an hour. Refreshments are available at 4:00 p.m. Visitors are welcome. Stop by to find out the latest details about some fascinating science! There is no colloquium on Thursday, January 28 Next Event | Feb 4: STRUCTURAL HEALTH MONITORING: A STEPPING STONE TO DESIGN OF SMART STRUCTURES |
Dr. F.K. Chang, Stanford University - Director, Structures and Composites Laboratory  Structural health monitoring (SHM) involves not only multi-disciplinary engineering from sensors/actuators, materials, structures, and diagnostics to system integration, but may also result in a paradigm change in design, manufacturing, and maintenance practice for structures. Recent advancements in SHM technology have demonstrated a significant progress in the technology toward practical applications. The formation of worldwide Aerospace Industry Steering committee for SHM (AISC-SHM) further indicates an industry-wide commitment to the SHM development and implementation.
It is anticipated that with adequate SHM technology, structural conditions could be monitored automatically and residual life could be predicted while the structures are in service. Optimal structural performance could be achieved in operation because the actual structural conditions are better known in real time and because the structures are better designed to account for uncertainties. These structures shall only be maintained when needed, thus significantly reducing maintenance costs.
This presentation will review recent highlights in SHM technology with which the PI has been involved, with an emphasis on quantification and validation that are new challenges that still deserve much needed attention from the SHM community. It will also give a review of recent focus on transferring the SHM technology to the development of bio-inspired autonomous flying vehicles.
