*

Calculated at specimen stress level of 1.0 MPa.

**

Calculated as the slope of the linear part of the stress-strain curve.

***

Calculated as the slope a fitted line through the portion of the stress-strain curve between stress levels of 0.4-1.0 MPa for circumferential specimens and 0.05-0.1 MPa for radial specimens.
