(A) The dimensions of the dog bone-shaped cranial dura mater specimens are depicted. (B) The determination of the biomechanical parameters in this study is shown in a representative stress-strain curve of one of the cranial dura mater samples that were tested in this study. The elastic modulus (Emod) was calculated through a linear regression analysis between the zero-point and the point that equals 70% of the maximum force (Fmax). Ultimate tensile strength (UTS) is the maximum stress (Fmax divided by the cross-sectional area) before tissue failure when being strained. Strain at maximum force (SFmax) depicts how much the sample was strained at the point of the UTS compared to its initial length.
