Effect of a longitudinal cut on the mechanical properties of small-diameter roundwood of Pinus nigra Arnold

The use of roundwood in structures has drawbacks that include tapering and lack of flatness, which can be overcome by making a longitudinal cut to flatten one side. The aim of this work was to compare the mechanical behavior of roundwood vs. roundwood with one flat face, comparing pieces of small-di...
