Hi everybody!
In a contact analysis in Abaqus, you should always have a denser slave surface than master so you don't experience penetration. I found this picture to illustrate: https://www.sharcnet.ca/Software/Abaqus/6.11.2/books/gsa/graphics/gsx-pure-mast-slave-nls.png .

As I understand, shear locking usually happens with long, thin elements with high bending. My shear test only have a displacement of o.3 mm of a 40mm long pin.
Hi everybody. I'm doing a shear test of a pin. Today I stumbled upon an something interesting. With C3D20 elements, I get a stress of 710 MPa and with C3D8 elements I get 370 MPa. Even if I use finer C3D8 elements it will not get as high as 710 MPa. Anyone know a reason for this?

Hi everybody.
I'm a little stuck with a problem. I use a displacement boundary conditions applied to a reference node. It is very similar to what this video does: https://www.youtube.com/watch?v=soYwaW54WRg
The problem is when I use the same equation constraint my part doesn't move (nothing...
I did it with rigid shell elements instead. This worked much better, but I still have a few problems. With a solid cylinder the job runs but the first few steps of the visualization, the parts shifts acoording to eachother, I attached a picture. When I run a model with a hollow cylinder, I get...
Hi Guys!
I'm trying to bend a pipe in Abaqus. I following this video: https://www.youtube.com/watch?v=soYwaW54WRg on my model in the picture attached. I'm using the block on top to bend the pipe underneath. The job runs and completes but nothing happens and I have the following error messages...
