Definition of a Physics-of-Failure Model
Models submitted to WARP must meet the following criteria for approval:
  • A quantitative mathematical model.
  • Identifies a root cause failure mechanism.
  • Identifies the environmental stresses that accelerate the failure mechanism.
  • Model's parameters are based on test, field and/or simulated data.
WARP's Objective
The objective of the WARP effort is to collect, analyze and verify the existence and characteristics of physics-of-failure (PoF) models for electronic, electromechanical and mechanical components to provide a centralized web-based repository within the RIAC that is accessible to researchers and engineers.
