Sorry to bother again. I created a new part which is the cohesive layer. I constrained (tie) it the other 2 parts. However, Abaqus isn't able to solve the first increment (two severe discontinuity iterations in each cutback). Any idea what could be wrong?

This is my model. Thanks for the tiphttps://files.engineering.com/getfile.aspx?folder=fa1bb140-c4d5-4c9a-ac8e-a0fd5331cd8b&file=Job-1.inp

Yeah I understand that. I might have not made myself clear. I wanted to know if it possible to create a contact interaction between an exterior face of a part and an interior surface (created by a partition) of another part

I partitioned the part, added a cohesive section and COH3D8 elements in the mesh.

Hi. I have 2 components connected with a cohesive layer in between. The cohesive layer is modelled in one of the parts, using of a cell partition. The cohesive layer has a tie constraint with the other part. I want to had a contact interaction between the two components, to prevent penetration...

Thanks for the answer. just to clarify, in Abaqus Standard the no-penetration between the adjacent components needs to be modelled (for instance with a normal hard contact interaction)?

Hey. I have two components connected by a cohesive layer (using cohesive elements). The cohesive layer is then fully degraded. I haven't changed anything regarding element deletion or contact between the two components. Is there any chance there can be penetration between the two components...

My doubt was just about penetration. Thank you.

Hey. I modelled a contact cohesive interation between two components with a normal behaviour as well. When the damage reaches 1, is there penetration between the two components? As I didn't contrain them, I'm not sure if without the cohesive they penetrate each other. Thanks for the help

I haven't adjusted any coordinates, but I believe they are in the same plane already. I do obtain values for the stresses, but they don't very accurate. Also, Abaqus doesn't return SDEG outputs.

Hey. I am studying a huge structure in which I use multiple cohesive elements "surfaces" to simulate glue. I created the by partitioning parts and then tied them to the second part they were attached to. When I see the results of the job, the cohesive elements don't deform (no displacement) -...

Yeah, it's Abaqus. Checking the INP I found some surfaces with node type. Thanks for the help

Hey. I am running a simulation and I get multiple "Slave surface is a node-based surface used with surface to surface approach. In order to obtain improved stress accuracy with this approach, an element-based surface should be used instead." When I created the constraint I selected surface both...
