Abstract
  One of the problems of non-destructive tests in the detection of the inhomogeneities in wood and wood products is their location relative to the vibrating node and antinode. Thus, the hidden inhomogeneities located at the vibration node in such materials may not have any effects on the dynamic modulus ...  Read More

The possibility of estimating some of the acoustical properties of particleboards using plate mechanical vibration test

Volume 28, SPRING 1 , March 2013, , Pages 89-96

https://doi.org/10.22092/ijwpr.2013.3089

Abstract
  The possibility of estimating some acoustical properties of particleboard panels such as "Acoustical coefficient" and "Acoustical Converting efficiency" using vibrational non-destructive techniques was investigated. Particleboard plates with the dimensions of 50×50, 100×50 and 150×50 ...  Read More
