Founding Chair of the International Aerospace Industry Steering Committee for Structural Health Monitoring (AISC-SHM); Fellows of American Institute of Aeronautics and Astronautics and American Society of Mechanical Engineers. Abstract: The structural health monitoring (SHM) community has long been focused on diagnostic techniques based on sensor data for detection and monitoring of damage in various structural platforms. Due to recent significant progress in maturing SHM technology, considerable efforts have greatly been emphasized on its reliability of detection and quantification of damage. Numerous methods and techniques have been proposed for quantifying the probability of detection and damage localization and sizing. With improved SHM performance in reliability and accuracy in damage quantification, it becomes much more apparent that the SHM diagnostic results could be integrated with existing prognostic methods to provide more accurate and reliable predictions on the remaining life and integrity of the damaged structures in a real-time basis through continuing the monitoring of the sensor data from SHM systems. This presentation will review the current progress in structural health monitoring with a particular focus on acousto-ultrasound techniques for monitoring and quantifying the integrity of metallic or composite structures and multifunctional composite structures with embedded batteries from the Structures and Composites laboratory at Stanford University.

Tutorials(1) Using Fractional Failure for Reliability Assessment under UncertaintyTutorial Speaker: Dr. Feng-Bin (Frank) Sun, Tesla Inc. Bio: Dr. Feng-Bin (Frank) Sun is currently a Senior Staff of Reliability Engineering and Technical Lead of Manufacturing Reliability at Tesla Inc. with over 30 years of industry and academia experience. Prior to joining Tesla, he worked at HGST, a Western Digital Company, as a Senior Technologist of Reliability Engineering from 2010 to 2015, at Western Digital Corporation as a Technical Team Leader from 2003 to 2010, and at Maxtor-Quantum Corporation as a Senior Staff Reliability Engineer from 1997 to 2003. He has published two books, both by Prentice Hall, and more than 50 papers in various areas of reliability, maintainability and quality engineering. He received his Ph.D. in Reliability from University of Arizona. Dr. Sun served in the editorial board as an Associate Editor for the IEEE Transactions on Reliability from 1999 to 2003 and from 2016 to present, Program Chair of ISSAT International Conference on Reliability and Quality in Design since 2014, and a committee member and session moderator of numerous international conference on reliability. He is a member of ASQ and the President for Society of Reliability Engineers (SRE) Silicon Valley Chapter. He is also the program manager in charge of ASQ Reliability Webinar Mandarin Series. Dr. Sun received the RAMS 2013 A.O. Plait Best Tutorial Award. This tutorial is developed based on numerous publications of the author since 1994. In classical reliability engineering and life data analysis, the state of an item is binary: survive or fail (“1†or “0, “S†or “Fâ€). The number of each state, or the number of failures or survivors, is always an integer. For example, a 6-week life testing of 100 units yielded 5 failures and 95 survivors. However, in real world practice, fractional failures, and therefore fractional survivors as well, can be encountered at various scenarios. For example, the number of chargeable failures is fractional when
It may be seen the above scenarios share one thing in common; i.e., the state of the subject in study is not known or uncertain. However, engineers and management often have to conduct reliability growth trend projection, risk assessment, and decision making under such scenarios. Conducting scientific reliability analysis of the above scenarios requires proper status classification, modeling structure, and handling of the data entry by the reliability analysis software. Fortunately, as indicated in the tutorial that using MLE parameter estimation as an example, it is not too big a task for most reliability related software in the market to accommodate fractional failures. Some of them can already handle such scenarios (but with different data entry formats). The key is for the reliability practitioners to realize the existence of the fractional failures and survivors, quantify their likelihood, enter the data correctly, and interpret the results properly. Numerical examples are given, with the most popular commercial software in the market, such as Weibull++, JMP, and Minitab, to demonstrate the actual application in the real world practice including data collection, failure classification and fractional failure determination, data entry format, life distribution parameter estimation, reliability quantification, and field risk prediction. It is the author's experience and belief that fractional failure will become a norm, instead of an exception, due to the nature of failure initiation, development, and manifestation, effectiveness of corrective actions, failure-physics based identification of the sub-healthy condition using parametric degradation analysis techniques, failure analysis resource and capability limitation, etc. This is especially true with the advancement of failure physics, sensing technologies, and big data. It is hoped that this paper will be beneficial to a wide audience including reliability engineers, theorists, and management.
