measuring longitudinal elastic modulus bamboo through Project Details
| Abstract |
This project tests a non‑destructive, dynamic method for finding the longitudinal elastic modulus of bamboo, which is a highly anisotropic natural fiber‑reinforced composite. Because bamboo’s strength depends a lot on how its fibers run along its length, knowing its stiffness accurately is crucial for structural engineering. The method uses free‑vibration testing. Bamboo samples of different lengths are set into bending vibration, and their acceleration over time is recorded. A Fast Fourier Transform (FFT) processes these acceleration signals to pull out the damped natural frequencies and periods. These dynamic values are then plugged into the basic Euler‑Bernoulli beam equation to calculate the dynamic modulus of elasticity. To check the dynamic results,
static three‑point bending tests are run on the same specimens but with different loading setups. The comparison looks at how well the dynamic elastic moduli—usually between 14.1 and 16.7 GPa—match the static test values. Overall, this approach gives clear guidance on using non‑destructive evaluation to measure the mechanical properties of bio‑based composite materials.
