Concrete
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.
The failure criteria are described in the theory section:
Concrete Model
Select a Concrete criterionBresler-Pister, Willam-Warnke, or Ottosen. The defaults are taken From material. For User defined choices, enter other values or expressions.
Bresler-Pister
The defaults for the Uniaxial tensile strength σt, Uniaxial compressive strength σc, and Biaxial compressive strength σb are taken From material.
Willam-Warnke
The defaults for the Uniaxial tensile strength σt, Uniaxial compressive strength σc, and Biaxial compressive strength σb are taken From material.
Ottosen
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.
Tension Cut-Off
If required, select either None or Principal stress cut-off (see Tension Cut-Off).
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.
