Shear Visualization

Post by GianmarcoManzo » Sun Dec 01, 2019 5:51 pm

Hi all,
How can I visualize the shear on the element? With section.force I can see only Axial, bending moment and torque moment
thx

Hi Gianmarco,

If you want to visualize the shear component at the section level, you should include the shear in the section description:

Before you created a fiber section and you directly used that in the special_purpose.BeamSectionProperty. In this way the section can only describe P-My-Mz.
What you should do instead is to use the sectionAggregator. there you can use the fiber section for the P-My-Mz components and you can explicitly use a uniaxial material (either elastic or not) for the shear and torsion components.

Let me know if you have any issue using the section aggregator

OK. I have tried tu use section integrator. I have created in order:
- material
- fiber section
- section aggregator
- special purpose.beam.section.proprety in witch I have set the section aggregator tag
I have assigned to the element and at last I have created force.beam.column element. Is it correct?

Yes, those are the steps in the correct order.

As you noticed, when you use a fiber section in the aggregator, the P-Mx-My components are coupled (due to the fiber section). On the contrary, the shear components are uncoupled from each other and from other (P-Mx-My) components, since they are simple uniaxial models.
