Dear experts,
I am simulating the crack progressing in a concrete beam with the failure criteria for concrete (e.g., Ottosen) using COMSOL Multiphysics. The beam is loaded until some cracks are occurred. Next, I want to conduct the Modal Analysis of the damaged beam for which damaged concrete elements should be removed. Any suggestions for this problem?
I am thankful for your kind helps.
best,
Huynh
