In the Concrete subnode you define the properties for modeling materials with failure criteria representative of concrete. This material model can be used together with
Linear Elastic Material and
Nonlinear Elastic Material. It is available with the Geomechanics Module.
Select a Concrete criterion —
Bresler-Pister,
Willam-Warnke, or
Ottosen. The defaults are taken
From material. For
User defined choices, enter other values or expressions.
When Principal stress cut-off is selected from the list, enter a value or expression for the
Maximum tensile stress σt. Use this to constrain the concrete model with an extra yield surface, which limits the maximum principal tensile stress.
