How can you determine that an object will break, when the result in it's maximum stress exceeds the ultimate strength of the material while the displacement result is only 8.8mm that obviously shows that the object can still resist the load...
Im desigining a beam to column connection, with a load of 7 tons on the beam end, consider a cantilever loading, the result is on the pictures attached.

Your maximum stress appears to be concentrated in a very small area. I'm not an expert on stress analysis, but a model defect, or mesh error can cause such a concentration and lead to a failure.
This may be a good example of the software telling you something (there is an error), Instead of telling the answer you anticipated.
Could you upload the beam models? Then someone who is great at analysis could look at the problem area instead of guessing from the screenshots.
