Presentation Title:

Overview and 
     Purpose:

This presentation provides an overview of two physics-of-failure case studies. The case studies address physics-of-failure applications to electronic circuit cards and vehicle structures. Each case study outlines the data required to perform the analysis, the testing to provide model input and validate the analysis and the benefits of performing the analysis. The electronics case study describes the vibration, thermal and fatigue analyses conducted for circuit cards in a tri-service radio used for aviation applications. The vehicle structures case study involves a fatigue analysis of an Army trailer’s drawbar using dynamic simulations to provide the loading.
