Finite element model of bamboo culm ( Phyllostachys sp.) and its comparison to two experimental tests

The main goal of the work was to build up a general parametric finite-element model of a bamboo culm in ANSYS computational system. Subsequently the model was compared to a experimental measurements of chosen mechanical properties - three point bending test and brasil test. A parameter being compared was a force, which is necessary to exert to deform a sample on given strain. In this work two parametric models were created. First one is including dividing barrier - diaphragm. A mesh of the culm wall is mapped and is divided into three layers with different orthotropic material models in cylindrical coordinate system with respect to the culm axis. By contrast the barrier - diaphragm - is represented by free mesh with isotropic material model. Both FE models are fully parametric and three-dimensional. Hence they are very well utilizable for both further research of the bamboo itself and constructions from it.
