Mehrab Madhoushi; Hamid Hatefnia

Volume 37, Issue 3 , September 2022, , Pages 217-228

https://doi.org/10.22092/ijwpr.2022.357593.1709

Abstract
  In this study, ground penetration radar (GPR) was used to assess the internal defects and decay of structural old timber in buildings and compare it with the sound wood. For this purpose, twelve samples of three wood species of beech, oak and yew with dimensions of 120 × 60 × 400 mm, and ...  Read More

Volume 36, Issue 3 , August 2021, , Pages 256-263

https://doi.org/10.22092/ijwpr.2021.352061.1639

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
