Failure Criteria

Failure criteria normally predict the failure of a material subjected to multi-axial state of stresses. The Factor of Safety Wizard assesses the safety of the model based on a selected failure criterion.

A material may behave in a ductile or brittle manner depending on the temperature, rate of loading, chemical environment, and the formation process. No single failure criterion is best applicable to a material under all conditions. You should use all the information available to you about the material to select a failure criterion. You can try more than one stress criterion to assess the safety of the model.

The software supports the following four failure criteria:

For models with composite shells, see Composite Failure Criteria
