Design of humidity sensitive wooden materials for multi-objective application
2004
Brauns, J. | Rocens, K.
This study is devoted to the estimation of hygromechanical and mechanical behaviour of different systems of continuous layers (veneers) or layers consisting of wooden flakes. The hygroexpansion and warping of wooden composite depends on the moisture content and material configuration. Hygrodeformation in the board plane is a dimensional problem and can cause buckling due to restrained linear expansion, whereas thickness swelling has a deteriorating effect. Methods of predicting how humidity, material structure and various loading parameters affect the behaviour of layered wooden materials are displayed. The optimum orientation of layers for hygromechanical properties may not coincide with that for mechanical properties, thus for every type of loadinghumid environment, biaxial compression or flexureboards with a definite structure should be designed.
