Aims
On completion of this TLP you should:
- Recognise the stress and strain tensors and the components into which they can be separated.
- Know how to diagonalise a stress tensor for plane stress, and recognise what a principal stress tensor is and why principal stress tensors are useful.
- Understand what a yield criterion is and how it can be used.
- Have an appreciation of different yield criteria and the materials for which they are appropriate.
