We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi! Thanks for your help. I have tried adding the command. Although it changes the load deflection curve, there are still some drops. I tried varying the parameters and some variations remove the sudden drop, I am still trying to figure it out. However, I would like to ask another question regarding beam failure.

 

My model has fairly accurate results as compared with my reference load-deflection curve. However, I do not know how to determine when the beam will fail. In my reference study, the beam is supposed to crush due to flexure at a deflection of ~35 mm but my model continues to deflect at 50 mm (maybe even more if I increase my displacement control). How will I know if my model has failed due to flexure? What result will ANSYS give if my beam has crushed? Also, are there plots I can make to see its cracking or at least potential areas where cracking can occur? 

Thanks!
