Abstract
The dependence of elastic and tensile properties of coniferous trees on the share of summer wood can be presented as linear functions, if the soft wood is considered as a statically indefinite structure. By eliminating the share of summer wood by a certain function presented in the article, the elastic and tensile properties are the linear functions of density.
The functions are proved right by conducting strength tests on pine. Practical implications of the derived functions in rating the quality of wood are also presented.
The PDF contains a summary in Finnish.
