| Abstract: | Tree mechanical model is the key factor to tree stress analysis and mechanical properties testing.This paper described several representative tree mechanical models,introduced the research development and related assumptions and simplifications,and summarized the main problems in this field.It also discussed the future research applications and trends,and advanced some suggestions on the assumptions on trunk,root anchorage,wind field,deformation and damping,which would accumulate relevant experience for the future research and promote the development of tree mechanics. |
