Hi,

I`m New to Solid Works Simulation, and I have got a question.

See Picture of a beam and plate structure below. Results plot shows von Mises of Maximum 228,2MPa.
Yield stress for material (steel quality S355J2) is 355MPa, material factor 1,1 so allowable stress is  322MPa.

However factor of safety plot shows Min FOS: 0,89. I would expect that Min FOS was: 322MPa/228,2MPa
= 1,41. Does somebody know why the FOS is less than 1,0, even when the von
mises stress is far below allowable stress?
