Hello,
the design team thought they would try something new today.
The green sheet metal was inserted into the cantilever to reduce the deflection.
A "larger" beam was not possible due to lack of space.
Now I don't know; can RFEM-6 model the sheet metal for me? Or is there a way to calculate the deflection (with sheet metal)?
Otherwise, I still have the idea of creating a second member and increasing the section modulus individually from the node.
Regards
Maik
Hey Maik,
for your goal – that is to reduce the deflection – it is best to model the green sheet directly as a surface in the main model.
Create the plate as a steel surface with the appropriate thickness and rigidly couple it via the edges to the support and cantilever.
This creates a realistic composite action, and you automatically see how much the sheet contributes to the stiffness.
If you only want to check it roughly, you can alternatively split the cantilever from the node and assign a higher stiffness in the first section.
This also works for a quick estimate but does not represent the load paths quite as realistically.
I’m happy to help if you have any further questions.
Best regards,
Ann-Kathrin Dannwerth
