Course Description:
Inspired by the non-traditional excitations of pneumatic random shock (RS) machines and the product response-driven nature of the HALT (Highly Accelerated Life Tests) and HASS (Highly Accelerated Stress Screening), applying a Fatigue Damage Spectrum (FDS) in provides a tool for management and analysis of these processes. Overcoming decades of shortcomings, a Fatigue Damage Spectrum and its scalar FDS sum, can be used beyond generating and accelerating equivalent damage random test profiles.
Damage domain tools can benchmark RS excitations and product responses to correlate multiple applications within the HALT/HASS and ESS process to facilitate decisions. Metrics can complement anecdotal HALT/HASS results. FDS and the ∑FDS can also be applied to ED shakers used to benefit from ESS, HASS and even HALT.
The course is not a HALT/HASS tutorial and is vibration-oriented only, acknowledging the importance of thermal and power cycling or other stimuli or detail UUT failure modes. Define opportunities and inter-relationships. Although FDS and ∑FDS are Imperfect metrics, they incorporate relevant variables to decision-making by improving upon the inadequate frequency domain tools that lack validity and relevance for real-life, and especially RS vibrational excitations. The FDS characterization of severity and cumulative damage can be interpreted as relative product strength or robustness.
The course will provide examples of HALT/HASS process applications, RS system characterization, End-Use-Environments (EUE) and ED shakers, thus quantifying severities of different excitations and product field performance for Analysis including reliability.
Attendees will receive the complete presentation deck and are invited to submit questions and suggestions to enhance their benefit from the Damage Domain.
About your Instructor:
Steve Smithson is the founder and former President of Smithson & Associates since 1983. Steve holds a BSME from the University of Michigan and an MBA from Arizona State University. He served with MTS Systems Corporation as Director-Eastern Europe.
In 1990 and 1991, Steve introduced the fundamentals of Shock Response Spectrum to address the high peaks of the pneumatic shaker excitations and the need to incorporate stress cycle-counting to view as stress, UUT strength and dynamic severity. Relevant past experience includes representation of GHI Systems, Hobbs Engineering and QualMark Corporation. Smithson & Associates currently represents Vibration Research controls, ETS Solutions ED shakers, TestSmart chambers and shock test systems and Instrumented Sensor Technologies ruggedized field data recorders. Steve has presented numerous papers at ASTR and ESTECH and has published about fatigue metrics in two Sound & Vibration articles.
