Hi all,
I have just recently started writing the subroutines in Abaqus specifically the UMATs..I recently wrote a Umat for Yeoh model which is working fine...Now I want to implement a damage fuction (ETA) in this Yeoh model..I know that UMULLINS subroutine has to be chosen to implement the damage function...But I want some help with writing this code..Firstly how can I show the load increments in UMULLINS which is needed to update the strain energy density function from time to time to use it finding eta value..If any of you have already written the Umullins earlier then can you please share your code with me ....One more doubt I have is that can two different subroutines be used together in the same file...Does it work fine..If yes then how can it be done or if not then what are the other alternatives for the same.. Waiting for early replys..
You guys can also mail me sidswami [at] hotmail.com
Thank you.
