Problems for Chapter 9
Modeling Material Failure
9.1. Overview of Failure Mechanisms
9.1.1. Summarize the main differences between a ductile and a brittle material. List a few examples of each.
9.1.2. What is the difference between a static fatigue failure and a cyclic fatigue failure?
9.1.3. Explain what is meant by a plastic instability, and explain the role of plastic instability in causing failure
9.1.4. Explain the difference between `High cycle fatigue’ and `Low cycle fatigue’
9.1.5. Summarize the main features and mechanisms of material failure under cyclic loading. List variables that may influence fatigue life.
