Revision as of 07:58, 8 January 2014

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

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

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
