The Menetrey-Willam material model is contained in the Geomechanical Toolbox data item. This property supports Static Structural and Transient Structural analyses. It is useful for modeling geomechanic materials such as concrete. For additional information, see Menetrey-Willam in the Material Reference.
Menetrey-Willam Base and Dilatancy Angle are the primary properties and includes the following physical properties:
Menetrey-Willam Base
Uniaxial Compressive Strength
Uniaxial Tensile Strength
Biaxial Compressive Strength
Dilatancy Angle
In addition, once you insert the Menetrey-Willam model, the Menetrey-Willam - Additional Data data item displays in the Toolbox so that you can add Softening (Linear or Exponential).
