  hello,,
  
  i am working on simple structure (steel plate) like the photo below. I want to see failure on the structure when it reach its ultimate tensile strength (460 MPa). i have used commands (APDL) to kill elements when the stress is above the ultimate strength, but it did not work.
  
  As you can see in the photo, the max stress reach 600 MPa, however the elements are not disappear.
  
  Can someone tell me whats is wrong with my model?
  
  thank you.
  
  Regards,

  Dear Peter,
  
  I'have seen your discussion about ekill and i've tried it on my model.
  
  However, is your simulation based on fail strain or fail stress?

  The ekill script is based on Total Strain exceeding a threshold value.
