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 Uniaxial tensile strength σt, Uniaxial compressive strength σc, and Biaxial compressive strength σb are taken From material.

The defaults for the Uniaxial tensile strength σt, Uniaxial compressive strength σc, and Biaxial compressive strength σb are taken From material.

The defaults for the Uniaxial tensile strength σc, Ottosen’s parameters a and b , Size factor k1, and Shape factor k2 are taken From material.

If required, select the Include tension cut-off check box (see Tension Cut-Off). Enter a value or expression for the Max tensile stress σt. Use this to constraint the concrete model with an extra yield surface, which limits the maximum principal stress.
