Modeling three-point bending with crack initiation and growth

  I am trying to model a three-point bending test. I want to record the displacement and force on the top bar. Modeling the sample and the three bars with constraints and displacements is working well. However, at some point during the real-world test, the sample cracks and the force on the top bar drops. I want to model this crack initiation and fracture as well. How can I model this in workbench? It's a slow loading process so I am using static structural. n

  ,nYou could try following a methodology similar to https://journals.sagepub.com/doi/full/10.1177/1687814015591315, using a pre-cracked specimen. Let me know if this helps.nRegards,nIshan. n
