Hi, It depends on the material model and the whole simulation. You can, for example, implement it directly in UMAT. The procedure was described in this famous article "Wilson, W., et al. "Stresses in the local collagen network of articular cartilage: a poroviscoelastic fibril-reinforced finite element study." Journal of Biomechanics 37.3 (2004): 357-366". BR Seyed Shayan Sajjadinia
