Reply To: Reinforced concrete beam

Hello Mannie,

There are a few problems with your model.

You can't use no separation contact between your beam and the pressure plates on top or the blocks below because those bodies are free to slide around the face they are on since that is what no separation allows. You could bond them to the concrete, you you could simply split the face where those blocks touch and delete the blocks, fixing the three faces on the bottom and applying pressure to the two faces on the top.

The Analysis Settings only allowed one iteration per step. That is not recommended and there is a warning in the output file to that effect. I changed it to 1 step with 100 substeps.

 

I reduced the total force applied from 1,200,000 N (30 MPa on 0.04 m^2) to 20,000 N.

I put 3 elements across the thickness. I also added the code to plot the cracking.

 

You didn't say what version of ANSYS you were using. Attached is an ANSYS 19.0 archive.
