摘要

Softwood appears as a solid-type composite material at a length scale of some micrometers, while it resembles an assembly of plate-like elements arranged in a honeycomb fashion at the length scale of some hundreds of micrometers. In this paper, we elucidate the main load carrying mechanisms resulting from these different structural features by means of a micromechanical model, based on tissue-independent stiffness properties of cellulose, lignin, and water. The model comprises three homogenization steps, two applying continuum micromechanics and one the unit cell method. The resulting (orlhotropic) stiffness estimates deviate, on average, by less than 10 %from corresponding experimental results for a variety of softwood species.
