Library of Utility Functions for Structural Mechanics
When modeling materials for structural mechanics, there are many common operations that you may need, such as
•
Computing principal stresses and other eigenvalues
•
Matrix inversion
•
Converting tensors between matrix and vector representation
A large library of such utility functions which you can call from your external material function is available.
•
For a complete list of utility functions and how they are used, see
Using External Materials
in the
Structural Mechanics User’s Guide
.
•
For instructions how to include utility functions in your external material library file, see
