Factor | E (MPa) | εf (μm/μm) | σu (MPa) |
---|---|---|---|
Age | S | NS | S |
Orientation | S | NS | S |
S: significant difference (p<0.05); NS: not significant (p>0.05). E, elastic modulus along the transverse direction; εf, failure strain loaded along the transverse direction; σu, ultimate strength loaded along the longitudinal direction.
