Fracture Mechanics Characterization of Wood

Organized by

Stefanie Stanzl-Tschegg

A quantitative characterization of the fracture properties of wood is possible by using fracture mechanical principles. The inhomogeneous and orthotropic structure of wood has to be considered. Different experimental testing procedures and numerical methods will be presented. The effect of loading direction, mode of loading and environment on fracturing and cutting of wood will be studied.
