Description	For finite element modeling of wood-based composites (WBC's) can be used two different approaches. The first one is so-called morphological modeling meaning the WBC is first imaged in 2d or 3d and, then, transformed using empirical laws into FE model. The second approach that is more traditional, is based on a priori knowledge of properties and geometry of the WBC's. The goal of the work was to create parametric finite element model of oriented strand board (OSB) and study an influence of material properties and strands orientations on modulus of elasticity. For these purposes the two different techniques for building the FE model were used. The first model was built via volume entities (OSBVOL), but because of its high errors achieving ci. 600% due to a coupling of strongly heterogeneous meshes, it was rejected in the end. The second model (OSBMAT) was build via mapped finite element mesh using modified algorithm created in the first model. OSBMAT exhibited lower error in terms of modulus of elasticity than OSBVOL (ci. 69% and after the material properties adjustment it was only 1,21%). This proved that it is more suitable to model strand composites such as OSB using the mapped a priori prepared FE mesh.
