Sensitivity analyses of stem, root-plate and branches mechanical response
Original language description
Numerical investigation of tree structures is an increasingly used method for understanding its mechanical response to loading. The aim of this study is, with the use of the numerical methods, to find the significant parameters that influence the response of stem, root-plate and branches. The parametrical finite element (FE) models of stem, root-plate and branches have been developed in ANSYS Mechanical APDL (Ansys(R) Academic Research Mechanical, Release 2018, ANSYS, Inc.). Both of these models were validated and used for series of sensitivity analyses. The significant role of anchorage strength for both stem and branches was found, which implies the importance of consideration of not full-fixed anchorage in mechanical analyses. In the upper part of the stem and on the top of the branches the significance of tapering was observed. The importance of the position for observation of the relation between input and output parameters was confirmed also by the significance of elliptical cross-section to mechanical response in the middle part of branch. The higher significance of geometrical properties than material properties confirmed that the internal changes of material can be observed when the shape of the stem or branch is described precisely.
