Hello Everyone,

I am trying to model a representative volume element (RVE) at the mesoscopic scale for yarn-knitted hoses in abaqus. The geometric model looks something like this.

The "matrix" is a rubber compound, and the reinforcement is aramid (Kevlar).

I am stuck here. I would like your suggestions about how I can model the interaction between the reinforcement and the matrix.

1. If I use embedded elements in abaqus, I can easily generate hex meshes and can impose periodic boundary conditions easily on opposite faces. However, I want to know what happens to the volume of the reinforcement when using embedded elements.

2. I dont know if I can use Tie constraints. I really need to think about it.

I would love to hear some valuable suggestions.
