Biomechanical properties of rehydrated freeze-dried human dura mater tissues were studied. Scanning electron and polarized light analysis indicated a multilayered distribution of collagen fibers in the dura mater tissue. Uniaxial tensile testing of 95 test strips permitted determination of average values for failure stress (6.65±0.14 MPa), failure strain (0.15±0.003), tangent modulus (69.50±1.29 MPa), elongation (0.56±0.01), and tangent stiffness (12.53±0.24 kN/m) of the dura mater tissue.
