Abstract

The destruction of recombinant bamboo depends on many factors, and the complex ambient temperature is an important factor affecting its basic mechanical properties. To investigate the failure mechanism and stress–strain relationship of recombinant bamboo at different temperatures, eighteen tensile specimens of recombinant bamboo were tested. The results showed that with increasing ambient temperature, the typical failure modes of recombinant bamboo were flush fracture, toothed failure, and serrated failure. The ultimate tensile strength, ultimate strain and elastic modulus of recombinant bamboo decreased with increasing temperature, and the ultimate tensile stress decreased from 154.07 to 96.55 MPa, a decrease of 37.33%, and the ultimate strain decreased from 0.011 to 0.008, a decrease of 26.57%. Based on the Ramberg-Osgood model and the pseudo‒elastic design method, a predictive model was established for the tensile stress–strain relationship of recombinant bamboo considering the temperature level. The model can accurately evaluate the tensile stress–strain relationship of recombinant bamboo under different temperature conditions.
