General procedure of failure analysis: Simulated test service conditions and analysis of evidences — Lesson 5

This lesson covers the intricate subject of failure analysis and prevention. It delves into the general procedure of failure analysis, the importance of simulated service testing, and the relevance of these tests in failure analysis. The lesson also discusses the challenges of testing under simulated conditions and the potential issues that can arise. It further explores the importance of analyzing evidence collected during failure analysis and how it can help formulate the causes of failure. For instance, the lesson uses an example of a weld joint to illustrate how different evidences can indicate the primary cause of failure.

Key Takeaways

- Simulated service testing is crucial in failure analysis, but it comes with its own set of challenges such as the need for elaborate equipment and the difficulty in replicating actual service conditions.
- The analysis of evidence collected during failure analysis is vital in formulating the causes of failure.
- It's important to consider all evidence, not just one aspect, to get a comprehensive understanding of the failure.
