Experiments and Modelling of the Load Capacity of Green Wood

The material properties of green wood in the shaft vital trees differ significantly from generally known technically processed, dried wood. Furthermore, completely different residual stresses and fracture mechanisms are present natural full cross-section [1]. also depend on tree species. Our work focuses european beech (Fagus sylvatica). A large number experiments small test specimens [2]. We both, large-scaled specimens. Latter bending trunks with cross-section. Combining results considering micro-mechanical cellular components [3], a computational model is fitted to our experimental results. This aspect influences resistance should be representable model. particularly important order better assess risk building trees.
