Guide for Reliability Analysis Using the Physics-of-Failure Process

Ground Vehicle Reliability Committee
  • Ground Vehicle Standard
  • J2816_201804
  • Current
Published 2018-04-18 by SAE International in United States
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.

Use of Model Verification and Validation in Product Reliability and Confidence Assessments

Ground Vehicle Reliability Committee
  • Ground Vehicle Standard
  • J2940_201111
  • Current
Published 2011-11-16 by SAE International in United States
This SAE standard outlines the steps and known accepted methodologies and standards for linking Model V&V with model based product reliability assessments. The standard’s main emphasis is that quantified values for Model-based product reliability must be accompanied by a quantified confidence value if the users of the model wish to claim use of a “Verified and Validated” model, and if they wish to further link into business and investment decisions that are informed by quantitative second-order risk and benefit cost considerations.
