Summary:
With respect to a climatic changes the forest compositions are changing in favor of deciduous species. These changes are reflected also in industrial technologies that focus on processing of wood of deciduous species that have significantly different properties than wood of coniferous species. One of the main genus that is used in Czech wood-processing industry is beech. Beech has been well described within the scope of elasticity, but not sufficiently in plastic and fracture domains. The aim of this work is to characterize fracture behavior of bondline in beech wood composites. Beech-adhesive bond line will be analyzed using experimental and numerical approaches. Within the experimental part, all three fracture modes (tension, shear and torsion) will be analyzed using both standard and nondestructive optical techniques. Within the numerical part the finite element method implemented in software solver will be employed to predict the behavior of bondline at both micro and macroscale within the composite. To achieve that, material models of fracture and plasticity mechanics will be utilized.
