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.
Damage function
The Damage function defines the model for Mullins effect.
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.
For Miehe enter the following settings:
•
Maximum damage d∞.The default is 1.
•
Damage saturation Wsat. The default is 1 MJ/m3.
