Hello,
I am modelling a 2D cell of a composite material using ABAQUS. I created a single part and assigned two different sections to fiber and matrix and then studied the crack initiation and propagation through XFEM analysis. The results that I get are quite unrealistic, since the cracks seems to propagate withouth difficulty from the matrix into the fiber section.
How should I model the interface?
I would highly appreciated any ghelp, I am quite new to composite materials.
