Determination of elastic constants of recombinant bamboo for structural material using an electrical measurement method
Twelve elastic constants of recombinant bamboo were determined using an electrical testing method. Three poisson's ratios with a big variation coefficient were revised. The applicability of the electrical method for elastic constants determination was verified. At last, the elastic constants of recombinant bamboo were compared with those of several timbers. The results showed the relationship between elastic modulus of recombinant bamboo was ELERET and its coefficients of variations ranged from 12.723% to 28.944%. In addition, the elastic constants satisfied restrict conditions of the orthotropic model, but slightly large errors between test values and theoretical values were brought by the non-uniform distribution of bamboo bundles. The elastic constants of recombinant bamboo were much higher than those of timbers.
