Description / Abstract:
The Physics-of-Failure (PoF) is a science-based approach to
reliability that uses modeling and simulation to design-in
reliability. This approach models the root causes of failures such
as fatigue, fracture, wear, and corrosion. Computer- Aided Design
(CAD) tools have been developed to address various loads, stresses,
failure mechanisms and sites. PoF uses knowledge of basic failure
processes to prevent failures through robust design and
manufacturing practices, and aims to:
• Design-in reliability up front;
• Eliminate failures prior to testing;
• Increase fielded reliability;
• Promote rapid, cost effective deployment of Health and Usage
Monitoring Systems (HUMS);
• Improve diagnostic and prognostic techniques and processes;
and,
• Decrease operational and support costs.
This guide provides a high level overview of the methodology,
process and advantages to performing a PoF assessment.
