MESH REFINEMENT - ABAQUS - BONDED JOINTS

[Ranulfo Martins Carneiro Neto]

Hi everyone,

I'm working with bonded joints in Abaqus, modeling a single lap joint or similar. I know how to create partitions in substrates and adhesives, so I can get a better mesh (larger density) at the points of singularities (stresses peaks). I do not know yet how to get different sizes of mesh at the same partition. In the picture (attachment), see that lower elements are larger that upper elements, and it happens in the same partition. How do I do it?

Is there any tool to change the distribution of meshes at the same partition?

Thanks a lot.

As you can see at your image, a regular quad mesh has to be distributed and connected to the mesh at other faces. So the size changes a very limited. When you allow triangles (quad-dominated), then the mesher can respect local seed much better.
