Example calculation

Stresses at beams and welded joints (Extended Edition)

according to Halbehauer/Bodenstein "Maschinenelemente", Springer 1996

Attention:
Shear stresses are calculated taken into account all welded joints in difference to the origin algorithmus given in full version of the program.
The user have to check, if all welded joints will take the loadings.

Component:
(see Attachment 1 for Sketch)
