Syntax
Remarks
The isotropic damage is implemented.
The anisotropic damage is implemented.
For detailed explanations of parameters, please refer to 10.1016/j.ijsolstr.2013.07.008.
The default
CDPM2
uses isotropic damage, which is equivalent toCDPM2ISO
.The token
CDPM2ANISO
uses anisotropic damage.If damage is activated, both tension and compression use the exponential damage model, the degradation is controlled by parameters [14] and [15]. The characteristic length can be accounted for by modifying them.
Details of implementation can be seen in the corresponding section in Constitutive Modelling Cookbook.
Recording
This model supports the following additional history variables to be recorded.
DT
tensile damage
DC
compressive damage
Examples
The anisotropic damage uses the following expression,
Both damage types have physical implications. Depending on the damage type, the model parameters may be adjusted differently.
