Bending characteristics analysis and lightweight design of a bionic beam inspired by bamboo structures

In this paper, a bionic bamboo beam composed of bionic bamboo tubes and bionic bamboo diaphragms is first presented, which is inspired by the macro structures of bamboo due to lightweight characteristics of bamboo in nature. Then, the bending model of bionic bamboo beam is established on the basis of the Euler-Bernoulli beam theory. The correctness of the model is verified by comparing the results by its own compiled code with those by the...
