Hello everyone,
Does anyone have any experience/insight on RVEs where the fibers interlock, thus causing some contact to occur between the fibers of the matrix?
Please do let me know whatever idea you might have on this :)
I read relavent literature in the past, I think using the following keywords would help:
Interface; wettability; traction
In some cases the RVE is modelled as three regions, fibre, matrix, and interface region. In such case, you assume full interactions between all three regions, but obviously interface region will have specific properties to simulate the interface behaviour.
Another option is creating two different parts, fibre and matrix, then introducing constraints as the link between their contact surfaces.
I hope it helps a bit.
Hi Sadik!
Good to hear form you again. Thank you for that wonderful insight.
As of now, in Abaqus, I am using "Embedded" constraints where the fiber is embedded in the matrix. In Abaqus, as you know, the translational degrees of freedom are constrained for the embedded element. So although the fibres are placed really close to each other, contact is not taking place.
I will definitely look into the interface topic.
Also, kudos to you and your team on the EasyPBC tool! I have been using it in my spare time and trying out and it seems to be quite something. :)
