How Far Can We Control the Heterogeneity of Wood and Wood Based Materials Through Design ?

Wood is usually considered apart from other materials by engineers and designers, related more to nature than to artifice, to tradition than to modernism. Mechanical performances of wood, especially in bending, are well known, and have been utilised in load bearing structures from historic times. To be more precise some woods are known for their mechanical performances, and actually there is a tremendous variability of the properties of commercialised woods, the origin of which lies in the diversity of species, but also in the heterogeneity of production conditions. One can take advantage of this diversity, considering that different species have different mechanical properties that can be utilised for different purposes, but this requires a specific culture of “ doing with wood ”.
