Continuum micromechanics estimation of wood strength

Wood strength is highly anisotropic and tissue‐specific. We herein show how it can be predicted from local failure of the nanoscaled wood component lignin and from the microstructure and the composition of the wood tissue, by means of continuum micromechanics. The suitability of the model is confirmed by the good agreement between model‐predicted biaxial strength values of wood and corresponding experimental results. (© 2006 WILEY‐VCH Verlag GmbH & Co.
