Web23 mei 2024 · Fortunatelly, about the loads at the end of the beam I find a solution. Using two "weld joind", one for each beam end that connect the beam to the other elements of the structure, I am able to extract the forces and moment that act at the ends of the beam. In particular I use the "constraint forces" and "constraint torque" signals. Web29 dec. 2012 · One can note that von mises stress is at maximum towards the fixed end of the beam, and the value is 1.32×108 Pa. This is less than the yield point value of mild steel. So the design is safe. In short an engineer’s duty is to keep the maximum value of von mises stress induced in the material less than its strength. That's all in this article.
