Determination of the Combined Influence of Density and Knots on the Mechanical Properties of Full-Size Structural Timber

摘要

The mechanical properties of wood depend on the complex interaction of its intrinsic properties such as density and moisture content and its visible defects of which the most important are knots. To determine the influence of all these factors simultaneously is very difficult, thus the test methods which were used and the test conditions were selected in such a way as to eliminate as many of them as possible and confine the investigation to those factors known to have the major influence.
