Hi all,

Thanks.

HI Farhan,

  Basically, All 3 are material parameters used in the Damage function (the modified Ogden-Roxburgh damage function) and have the following functional form:

 

 All 3 are dimensionless and would make the material stiffer with increasing values (please see the attached picture).

Hope this helps.

Regards,

Sandeep
