Thank you.
A follow up question. Would plane stress still be achieved naturally if I use quadratic brick elements or is it only the case for linear brick elements?
I can easily wrap my head around the plane strain, but for some reason, I can't do the same for the plane stress. Is the argument...
Hi all,
I have a quick question regarding enforcing plane strain/plane stress conditions on 3D solid elements, e.g. hexahedrals or brick elements.
Lets say I only have a single layer of 3D solid elements in the z-direction.
There are no tractions applied in the z-direction.
The thickness of...
UPDATE:
(Model illustration - cohesive elements are placed in the scarf joint interface, while the rest are quadratic solid elements.)

It seems that I encounter a similar problem as when I use automatic stabilization.
The kinetic energy continues to increase beyond 5% as the...
OK here is my procedure so far. I will update you when the simulation is completed.
1) Added densitities for all my materials, carbon UD, carbon biax, glass biax by converting kg/m^3 to tonne/mm^3 by factor 10^-12, since I run everything in MPa, mm etc.
2) Performed an Eigenvalue analysis to...
Hi NRP99,
I will take a look at that.
Are there anything I should be aware of, i.e. material densities of the zero-thickness cohesive elements, time increment etc.?
With automatic stabilization, we would check to see ALLSD/ALLSE exceeded 2%-5%. Are there similar checks for implicit dynamic...
Hi,
My problem is related to the modelling of zero-thickness cohesive elements in a scarf joint.
My original plan was to use viscous regularization, but this causes the cohesive interface tractions to exceed the specified onset-traction values.
This is also unphysical and sort of throws a...
Hi everyone,
If you have any experience with using automatic stabilization I would like you help with clarifying something.
Is it possible to fix the damping factor used? I have noticed that the it is still possible for it to increase during each increment, which causes the dissipated energy to...
I currently get the following error: The local-1 direction (after the additional rotation and permutation) of the material orientation , specified via *ORIENTATION, is normal to the SHELL, MEMBRANE, GASKET, COHESIVE, or SURFACE element. The local-1 direction must be projected onto the element...
Yes, using the Assign Stack Direction tool is what creates the result in picture. It works everywhere except for the transition between the wedge and hex elements.
In fact, from the previous post, I can see that the same problem is encountered in the figures.
Here is the picture from the post...
Hi all,
I am trying to model a scarf joint using cohesive elements for the adhesive. The adhesive mesh is modelled using a mixture of wedge and hex elements to create a "structured" mesh.
Taking a look at the adhesive part, the way that this is accomplished is by assigning a structured mesh...
