Abstract

The main purpose of this study is to present the results of the testing and modelling of compression and heat-treated birch wood as constructional component. Using some special and some patented treatments the hardness and bending strength of components can be increased by up to fifty per cent. Since wood is macroscopically and microstructurally an orthotropic material, reliable prediction of its mechanical and failure behaviour requires verified models. Basic mechanical testing is made with samples to obtain strength and damage locations and modes. SEM pictures are used to reveal microstructural features. These test results and measured or estimate
