Figure 2 illustrates the data fitting by the
modified Hankinson formula, which subsequently
gives equation (2)
where UTSSW parallel to grain of solid wood was
50.91 MPa interpolated to SG = 0.7 (Puajindanetr
and Wisuttipaet, 2003). The coefficient of determination,
R2
, was 0.83. The longer strand length
(or larger slenderness ratio) has resulted in a
decreasing of stress transfer angle and, hence,
increase in the strength. UTSOSL is about 90% of
UTSSW as the slenderness ratio is 360.
