Numerical assessment of behavior of a historical Central European wooden joint with dowel subjected to bending

Popis výsledku v původním jazyce

In the Central Europe there are many historical constructions that contain various historical joints that do not contain any metal connectors. The lack of engineering standards for their design due to their reconstruction calls for detailed analyses of their behaviour. Therefore, the goals of this work were: a) to develop a contact finite element model of the ?oblique joint with a dowel; b) to numerically analyse the joint when loaded in 3-point and 4-point bending tests. The FE model was 3D and enabledto study hypothetical scenarios at different geometries, used materials. The FE model assumed orthotropic material properties of wood (Norway spruce) and elastic region of deformation, the contact was flexible-to-flexible and symmetric meaning the all parts of the joints could experience deformation. Results from numerical analyses revealed an influence of the a dowel vertical position in respect to the beam neutral axis on stiffness. The stiffness of the beam with joint increases as th
