Hi everyone, I only have the basics with FEA so I'm hoping this isn't a dumb question. I'm working with Strand7 and have a simple structure modeled (roughly an ovoid coming out of a flat surface) that will be deformed from a load pulling it to the side. It's a basic setup so far, using isotropic material properties and non-linear analysis. I was wondering later about how much force would be needed to cause a break in the structure, and found in the literature that the material used has a fracture toughness of 4.12±0.4MPam^1/2
(However, I've only done simple stresses / deformations / etc before and never had to deal with any fracturing. Can someone explain how I would go about doing this in Strand7? I'm not sure if this involves entering a stress/strain table into the model or if there's a way to calculate from the results I already have if the stress is "too much" in any location.
Thank you for any help!
