| Abstract: | Vibration-based non-destructive detection method is adopted to measure the dynamic elastic modulus of fiberboard which is compared with the static elastic modulus measured by a mechanical test machine.The results indicate that the dynamic elastic modules of fiberboard measured by the vibration method is of higher accuracy and that the correlation between the static elastic modules and dynamic elastic modulus is linear.A non-destructive detection system for detecting dynamic properties of fiberboard is estab... |
