Before you start - The basics
This TLP requires a basic knowledge of vector and matrix algebra, including scalar products, matrix multiplication, 3x3 determinants and suffix notation. The TLP includes a section which revises these concepts; you can skip this section if you do not need to cover this material again.
If you are unfamiliar with the concept of anisotropy in materials, you should follow the TLP on Anisotropy before starting this one.
Similarly, you may need to read through the Crystallography TLP to gain the understanding of crystal systems and symmetry elements which will be needed in order to follow the section on the effects of symmetry on tensors.
