This paper deals with research on the impact of material properties (material thickness and type) on stress/strain
curves of the layered materials based on hard and soft wood during bending. Reference curves, obtained for the
bending of real samples, were the base for the simulation. Subsequently, the recorded curves were imported into
SolidWorks application, where they served as the data source for the simulation. The results, as well as model
analysis of two-layer materials, have proven that the bendability is better for the composition with soft material
in the bottom layer. This can be explained by the fact that the soft material under tensile strength shows greater
deflections than the hard one before the breaking. For three-layer compositions, similar behavior can be concluded.
This part did not deal with connection among the layers. The paper gives a possibility to predict the behavior
of layered materials if the characteristics of its layers are known.
