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.

The defaults for the Tensile strength σts, Compressive strength σcs, and Biaxial compressive strength σbc are taken From material.

The defaults for the Tensile strength σts, Compressive strength σcs, and Biaxial compressive strength σbc are taken From material.

The defaults for the Compressive strength σcs, Ottosen parameters a and b, Size factor k1, and Shape factor k2 are taken From material.

If required, select either None or Principal stress cutoff (see Tension Cutoff).

When Principal stress cutoff 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.
