The elastic modulus is depicted in relation to the thickness of dura mater samples. Additional data to the colored sample pairs (A–D, pairs of an identical thickness) are: (A) age: 50 years, post mortem interval (PMI): 104 h, elastic modulus (Emod) = 31.50 MPa, sex: male, side: left, water content: 80.93%; (B) age: 36 years, Emod = 84.15 MPa, PMI: 88 h, sex: female, side: right, water content: 70.77%; (C) age: 77 years, Emod = 43.87 MPa, PMI: 57 h, sex: male, side: right, water content: 74.72%; (D) age: 43 years, Emod = 108.62 MPa, PMI: 120 h, sex: female, side: right, water content: 81.17%.
