I am currently engaged in simulating fiber damage within meniscus tissue, initiating with basic models to grasp the nuances of the software I'm using. Up to now, I've successfully modeled the damage to the viscoelastic material that represents the meniscus tissue matrix. However, I'm encountering challenges in incorporating fibers into the simulation. My approach has been to configure the model as a solid mixture, aiming to integrate fibers with damage, yet I struggle with managing the strain level at which the fibers fracture and adjusting the quantity of fibers that undergo this breakage. As an initial step towards testing the model's functionality, I'm attempting to synchronize the fracture strain level for both the matrix and the fibers, as well as having all the fiber break at the same time. Although I'm unsure if my current setup for the material properties is optimal, I would greatly value any insights or recommendations on how to accurately model the fibers and their damage.
I have attached my .feb file for both the viscoelastic model, the viscoelastic + fibers model and the viscoelastic + fibers model with damage.
