Abstract (EN): The single-edge-notched beam loaded in three-point-bending has been numerically analyzed to validate its adequacy to characterize wood fracture under pure mode I loading. This specimen geometry has been chosen since it is particularly useful to perform tests in those fracture systems impossible to be tested with the double cantilever beam (DCB). The study revealed several aspects avoiding the direct measurement of fracture toughness in wood due to confinement of the fracture process zone (FPZ) under loading. This has been confirmed analyzing stress profiles of different specimen sizes, differently affected by compression due to bending.
