The first step is the validation of Karamba3D by a comparison of multiple scenarios with analytical computations and Abaqus in static and dynamic analyses. Then the parameters influencing wood’s mechanical properties are evaluated to determine those that are to be included in the log model. Especially, a sensitivity study on wood’s orthotropic constants is carried out to assess the approximation of the material properties by an isotropic model. In parallel, an algorithm is created in Karamba3D to approximate the irregular shape of a log by four different methods that simplify the cross-section in cylinders. This algorithm was validated on simple geometries such as cylinders and cones. From the two previous steps, the scan of a real log is analysed in bending and vibration by Karamba3D and Abaqus. The comparison of the results enables to select the two best approximation methods from the Karamba3D algorithm. Thereafter, the impact of carving notches in a beam is compared in Karamba3D and Abaqus. In Karamba3D, a study was made to improve the algorithm by enabling it to analyze less regular cross-sections such as circular segment cross-sections. Out of this, a first draft of a floor model is created in Abaqus and Karamba3D. The two models are compared and a first analysis on the best way to model contact interaction in Karamba3D is conducted.Whole logTimberFinite ElementWoodAbaqusGrasshopperKaramba3DWooden floorRobotroncNumerical modellingRhinocerostext::thesis::master thesisthesis:35609
