5mm dia × 5 mm height. Deformation rate of 1.5 mm/min, modulus based on average slope of the lower portion of stress-strain curve (<15%).
6mm dia × 2.4 mm height. Deformation rate of 2mm/min, modulus based on average slope of the initial portion of stress-strain curve.
5mm dia × 1mm height. Load-controlled deformation rate of 40 to 100 mN/min.
12.5mm dia × 1.5 mm height. Load-controlled deformation rate of 25 mN/min, Young’s modulus equivalent to the absolute value of the slope obtained between initial preload force (.01N) to .25N.
6mm dia. Deformation rate of .5 mm/min, modulus based on average slope of the lower portion of stress-strain curve.
Deformation rate of 1mm/min. Elastic moduli were obtained from the slope of the stress vs. strain curves, limited to the first 10% of strain.
Equilibrium modulus calculated from the equilibrium stress and initial cross-sectional area at 10% strain.
