Chapter 8: Strain Transformation

Chapter overview

If strain is so closely related to stress, and if we can “transform” stress, then we must be able to transform strain too, right? But how?

That’s what we’ll be looking at in this chapter:

• C8.1 Equations of Strain Transformation - general equations to transform strain
• C8.2 Mohr’s Circle for Strain - the smarter way to transform strain
• C8.3 Generalised Hooke’s Law - calculating effective strain from multi-directional stress
• C8.4 Theories of Failure - criteria at which materials fail
