Abstract
The mechanical properties of broad-leaf tree species in a maritime-wind exposed habitat in central Japan were examined. The broad-leaf trees studied were Celtis sinensis var. japonica, Ilex integra, Eurya japonica, Pittosporum tobira, Euonymus japonicus and Cinnamomum japonicum. The results obtained can be summarized briefly as follows:
-
1.
At places with weaker wind, the number of species increased and the height of the canopy increased.
-
2.
The fracture strength σm showed no dependence on tree part or branch thickness, but was constant.
-
3.
The order of strength was Celtis sinensis var. japonica > Ilex integra > Eurya japonica > Pittosporum tobira > Euonymus japonicus > Cinnamomum japonicum, and these six species could best adapt to the wind pressure in the study area.
-
4.
Within species, fracture strength varied directly with wind strength.
-
5.
The strain εm decreased as the trunk became thicker.
-
6.
Within species, strain energy Um varied directly with wind strength.
