(a) 3D finite element model mesh (16800 hexaedrical porous elements C3D8P). mm. (b) Fibres direction in the plane. (c) Mesh axially compressed by 5% strain followed by a relaxation period. (d) Compression strain of 10% followed by 2500 s of relaxation, loading cycle repeated three times adding a 5% of deformation at each increment.
