“…The morphology of bamboo internodes has been less elaborated on because researchers have focused on bamboo culm as a sample rather than on the internodes [3]. Some examples of such research include bamboo culm form factor [12], [13], [18], bamboo culm volume [14], [16], [17], [33], [36], and culm bamboo biomass and carbon stock [7], [14], [30], [38], [39].…”

Most bamboo research has focused on growth performance, physic-chemical attributes, and biomass estimation. There are few studies on elaborating the biometrics of bamboo, especially in internodes mathematical expression. In this study, we revealed the mathematical expression of bamboo internode along the culm. We used 30 samples of culms and cut each culm by its internodes. A total of 928 sample internodes were measured for the outer diameter, wall thickness, and length of internodes. The findings showed that the mathematical expression for two-dimensional culm morphometric was a two and three-order function. In contrast, the three and four-dimensional culm morphometric were a four-order function. Moreover, the relationship between relative internode number (RIN) and relative internode length (RIL), and relative cumulated internode length (RCIL) showed a third-order function.

“…Nevertheless, certain species of bamboo, like Chimonobambusa quadrangularis (Franceschi) Makino, have a square-like cross-section along the whole length of the culms [9]. Figure 1a shows the cross-section of the square bamboo [10]. It is typically two or three centimeters in outer diameter [10], having a square cross-section with rounded sides and filleted corners, as schematically illustrated by Figure 1b.…”

“…Figure 1a shows the cross-section of the square bamboo [10]. It is typically two or three centimeters in outer diameter [10], having a square cross-section with rounded sides and filleted corners, as schematically illustrated by Figure 1b. Besides the square bamboo, many plants are known to have polygon-shaped cross-sections in their stems or branches [11].…”

Hollow-section columns are one of the mechanically superior structures with high buckling resistance and high bending stiffness. The mechanical properties of the column are strongly influenced by the cross-sectional shape. Therefore, when evaluating the stability of a column against external forces, it is necessary to reproduce the cross-sectional shape accurately. In this study, we propose a mathematical method to describe a polygonal section with rounded edges and vertices. This mathematical model would be quite useful for analyzing the mechanical properties of plants and designing plant-mimicking functional structures, since the cross-sections of the actual plant culms and stems often show rounded polygons.
