Advanced Accelerated Testing
This training provides a deeper focus on physics of failure and the theoretical and practical application of accelerated testing models. A brief primer on ALTA software (ReliaSoft) is presented as a method to estimate reliability at customer use conditions based on accelerated test results.
Prerequisite:
Recent (2 yrs.) completion of Introduction to Reliability Engineering & Accelerated Testing or an understanding of reliability testing principles and experience using Weibull++ software for analyzing test or field data.
Topics Addressed:
- General guidelines and assumptions
- Quantitative vs Qualitative approaches
- Time compression
- Acceleration Factor
- Sudden Death testing
- ALT models: Inverse Power, Coffin Manson, Norris-Landzberg, Arrhenius, Eyring
- Power Temp Cycling (PTC)
- Application of Damage
- Vibration testing
- Miner’s Rule
- ALTA primer (ReliaSoft)
- Degradation testing
- Cumulative Damage
- Proportional Overstress Testing (MEOST)
- Environmental Stress Screening
- HALT
Target Audience:
Reliability engineers, validation engineers, product development engineers, test engineers, and managers of these disciplines.
Delivery Method:
The training is designed to be interactive and conversational and delivered at the client’s location*. A number of in-class exercises are included to practice and reinforce the concepts. Bound training materials are provided to each class participant. Weibull++ software including ALTA Pro will be utilized for some of the exercises; Demo licenses are provided if needed.
* An option for remote delivery is available
Expected Outcomes:
At the conclusion of this training, class participants will be able to:
- Recognize the applications and limitations of accelerated testing
- Understand the most common methods to quantitatively and qualitatively accelerate a test
- Use Damage calculations to accelerate an existing test
- Design a Power Temp Cycling (PTC) test profile
- Design a basic ALTA test plan including sample sizes and stress levels
- Create a Proportional Overstress Test
- Design a Sudden Death Test
- Select an appropriate acceleration methodology for various test scenarios
