About the Instructor

Dr. Patrick Safarian, P.E.
Fatigue and Damage Tolerance Senior Technical Specialist, Finite Element Methods and Composite Material Professor

Since 1997, Dr. Safarian has been involved in ensuring safety of the existing fleet and certification of new airplane models, such as 747-8, 787 and 777-9, 737MAX and A350 at Federal Aviation Administration (FAA). His involvement includes new rulemaking activities, including Parts 25 and 26, plus preparation of the advisory circulars and training material for metallic and composite material structures. Prior to FAA Patrick was employed at the Boeing Company for eleven years as a stress analyst. During that time, he contributed to development of methods and allowables for fatigue and damage tolerance standards for stress engineers. He also performed analytical and computational stress analyses of highly complex structures, including failure analysis in support of airplane design, in-service problems and accident investigations.

Patrick received his BSME from Northrop University in 1983, MSME from California State University, Fullerton, in 1985, and completed his PhD work in Mechanical Engineering at University of California, Davis, in 1987. In June 2004 he completed his Doctorate in Theological studies at Bakke Graduate School. Patrick has taught damage tolerance and advance engineering mathematics courses while at Boeing for over ten years. He has been teaching post-graduate engineering courses in the fields of fatigue, fracture mechanics, finite element analysis and composite material at University of Washington and Central Washington University since 1998. He has been teaching two courses in fatigue and damage tolerance to the industry since 2008. He has also offered the industry courses in finite element methods and applications since 2017. Patrick is married to Annette and they have two children, Natasha and Christopher.

Dr. Safarian interacts constantly with the industry experts in developing and application of the latest simulations tools and provides key guidance to aviation industry in analyzing metallic and composite material structures.
