DETERMINATION OF FRACTURE TOUGHNESS FOR WOOD

In this study, the fracture toughness in modes I and II for wood were determined by methods based on the American Society for Testing and Materials standard 'plane strain fracture toughness of metallic materials.' The study proposes that crack initiation be done with a very thin blade saw, and a larger nonlinearity of the load-displacement curve is suggested. Fracture toughness values are given and their dependence on the material and experimental parameters is investigated. It was found that fracture toughness value for modes I and II was not affected by the moisture content of the specimens in the range of 10-20%.
