Introduction
This damage initiation law predict that failure initiates when maximum principal stress exceeds tensile strength of the material or when maximum shear stress exceeds shear strength of the material. Because it deals with principal stresses and tensile failure is the same regardless of direction, this law is only appropriate for isotropic materials such as IsoSoftening material.

This table lists the available damage initiation law. Click each one for more details and information on their properties.
| Name | ID | Description |
|---|---|---|
| MaxPrinciple | 1 | Damage initiates with principle stress exceeds tensile strength or when maximum shear stress exceeds the shear strength. |
It is relatively easy to write code for new damage initiation laws, if needed.
