Mullins Effect
Use the Mullins effect subnode to define the properties for modeling the stress-softening phenomenon under cyclic loading. The Mullins effect can be used together with Hyperelastic Material.
Shell Properties

 
This section is only present when Mullins effect is used as a subnode to Hyperelastic Material is used in the Layered Shell interface. See the documentation for the Mullins Effect node in the Layered Shell chapter.
Mullins Effect
The Damage function defines the model for Mullins effect. Select Ogden–Roxburgh or Miehe.
For Ogden–Roxburgh enter the following settings:
•
Maximum damage d∞. The default is 1.
•
Damage saturation Wsat. The default is 1 MJ/m3.
•
Deformation dependence coefficient α. The default is 0.
•
Select Use error function check box to define the damage evolution with error function instead of the hyperbolic function (default).
For Miehe enter the following settings:
•
Maximum damage d∞. The default is 1.
•
Damage saturation Wsat. The default is 1 MJ/m3.
