Nondestructive Testing of Wood
Nondestructive evaluation of materials, the science of identifying the physical and mechanical properties of materials without altering their end-use capabilities, is valuable in defining relationships between properties and performance of materials. Nondestructive evaluation techniques using these relationships have current industrial applications. They are used for machine stress rating of lu...
متن کاملNondestructive Testing of Wood Defects based on Stress Wave Technology
The wood samples were tested by the technique of stress wave, and the testing results were analyzed by using the statistic software of SPSS. The results showed that the length, density and knots of wood, the sizes of holes and numbers of holes have significant influence on propagation parameters and dynamic modulus of elasticity. Under the same specifications, the propagation time of the stress...

It stressfully introduces foreign contributions in the field in order to provide some useful references to the researchers.
متن کاملPerformance of Nondestructive Sonic Echo Testing Method on Partially Dismantled Unknown Wood Bridge Foundations; A Case Study
Sonic Echo (SE) testing method is a well-known, versatile method to gather information pertaining to unknown bridge foundations. Many studies on the applicability and methodology improvement of SE tests to evaluate individual piles and foundations supporting the superstructure have been reported previously. However, there is a rare opportunity for obtaining the performance of SE tests without t...
متن کاملTesting Exponentiality Based on Renyi Entropy of Transformed Data
In this paper, we introduce new tests for exponentiality based on estimators of Renyi entropy of a continuous random variable. We first consider two transformations of the observations which turn the test of exponentiality into one of uniformity and use a corresponding test based on Renyi entropy. Critical values of the test statistics are computed by Monte Carlo simulations. Then, we compare p...
