  Can you tell me how to use this TB,DMGI and TB,DMGE commands? I want to define the maximum stress as the damage criterion in tension and compression. there is no example in the help. I don't understand the help file.

  Hi
  
  I would suggest to try and do an example in WB mechanical, and then look at the TB commands generated in the ds.dat file . See here for a tutorial that might help:

  If you do that you will get like an example (Puck damage = 3):
  
  TB,DMGI,1,0,4,FCRT
  TBDATA,1,3,3,3,3
  
  also this is a very good resource:

  All the best
