Abstract: Timber beams with holes have been analyzed with linear elastic fracture mechanics. The energy release rate corresponding to the beginning of the crack growth is set equal to the external work done by the loading of the ...

Abstract: Determination of fracture toughness values in modes I and II for wood are considered. The testing methods are based on the American Society for Testing and Materials standard “plane strain fracture toughness of metallic ...

Abstract: The determination of the critical
