A Study on Strain Properties of Bamboo in Process of Heating and Cooling

Abstract:

Strain of bamboo affects remakably bamboo products. This study, through measuring strain of bamboo with the resistance strain measuring instrument, studied the radial and tangential strains of different height and sections of moso bamboo. The study indicated that the tangential strain of bamboo appeared mainly parabolic curve form, and the strain increased gradually from outside to inside part of bamboo wall in process of heating. The radial strain of bamboo increased gentlely with the temperature rising before 100°C, then rapidly increased after 100°C. The radial strain of bamboo increased gradually from upside to bottom of bamboo pole with the temperature rising too. The tangential strain of bamboo increased gentlely from 150°C to100°C, then rapidly increased from 100°C to 30°C in process of cooling, but radial strains at different height of bamboo pole presented mainly linear change with the temperature falling in process of cooling.
