The Traction Law

This traction law applies a linearly increasing stress and it never fails.

Failure

This traction does not fail; as COD increases, the traction increases. If you want to model failure, use a |trangular traction law instead.

Traction Law Properties

The following properties are used to create a linear traction law:

kIe The elastic slope, k, in mode I MPa/mm none
kIIe The elastic slope, k, in mode II MPa/mm none
