      Hi all,


      What represent r, m and beta (damage variable parameters) in Mullins effect?


      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
