Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2014-07-01 Abstract The exact derivation of the mode I geometric correction factor is given, based on the small crack merging mechanism to show that this always is the real fracture mechanism in wood. This mechanism dominates at late softening and explains fully the apparent decrease of the energy release rate of macrocrack extension as already known for mode I and is derived for mode II. The related exact theory, based on limit analysis, is discussed.
