Hi everyone,
please excuse the late reply. Thank you for your input.
It seems, that the overconstrained nodes were the problem in this case. I didn't expect them to have such a huge impact on the results.
Thanks again! :-)
I know that this is the solution that should come out of the simulation. But it doesn't, which is exactly the point. Only the shell model gives me the right solution. Not the one with hex elements, where I'm way above or below the expected solution, depending on if I use symmetry-BCs or not...
I tried everything. The mesh in the first .inp I posted is already pretty fine and structured. So this shouldn't be the problem. Also, since the "column" is only 10cm long, there shouldn't be any bending involved, so locking should not be a problem as well. However, I tried it with full...
Sorry, I forgot to attach the Model with shell elements. So here it is: Axial load is around 175 kN, so pretty accurate! https://files.engineering.com/getfile.aspx?folder=1bfe2359-a260-4109-833f-4c70377e70fc&file=Test2.inp
Hello everyone,
Yesterday I experimented a little bit with abaqus in order to understand different constraints. I noticed, that the numerical solutions for a simple model are very different to the results that I expected.
I created a VERY short column with an I-Shape cross-section. Now, since...
