Mechanical Properties of Structural Woods from Kyushu (V) : Kojii- and Tabu-wood Grown in Miyakonojo District

The authors tested on the mechanical properties of Kojii- and Tabu-woods (Shiia cuspidata Makino and Machilus Thunbergii S. et Z.) grown in Miyakonojo District, Miyazaki Prefecture, Kyushu. The following tables show the results of the tests. Ranges and average values of mechanical properties Average ratios of mechanical properties to density Mechanical properties were generally in direct proportion to the density, and their relations could be expressed by the equations (1)-(9) with Kojii-wood and (1)\u27-(9)\u27 with Tabu-wood
