Reaction force on cross section

Wisawanart

Hi

Yesterday, I have tried to determine the reaction force of the beam by applying the impact load (Drop test).

I defined the cross sections not only on the beam surface (shell element) but also on the impactor  (solid element).

After solving, I found that , the cross section on solid element shown the reaction force perfectly but for the shell element, it shown the worst result (oscillation)

and magnitude, These are shown as picture below,

How can I determine the  normal reaction force on the shell element by using cross section.

 

Thank you for your kindness

 

Best regards

Hi Nut,

A section is a cut in the structure, where forces and moments will be computed and stored in output files. You can create a output block (/TH/SECTIO) where this is recalled.

I'm attaching a document on sections where this is explained more.
