We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Thanks for the quick reply! Yes you are right, Wb,x,top is the secion modulus of the top flange. The generic equation for a rectangle shape is (width*height^2)/6. However the height of the top flange is only 2mm (see fig. 1, (40-36)/2. –> The top flange AND the bottom flange have a height of 2mm respectively. So in my opinion 26,67mm^3 is the correct section modulus for top flange (and of course also for the bottom flange).

So, still I don't know why I get this unrealisticly high stresses, when summing up sig_y,mean and sig_y :-(
