3D simulation of local mechanical behaviour of cohesion and damage between many fibers and matrix .

By a 3D many layers of curved fibers and matrix mixture we simulate the behaiour of the cohesion limit and beginning of crack and failure for different geometrical configurations and loads.

we investigate about a simple and realist damage model under propriety in abaqus.

fiber or resin fail dierectly from elastic to crack.

I ask if brittle crack damage option can be considered as a realistic crack and damage behaviour and how to set pparameters for carbon or glass fiber with epoxy r other resin?
