Nondestructive Evaluation of Wood using Ultrasonic Frequency Domain Analysis

In-situ performance assessment of wooden structural components are very important for maintenance and rehabilitation of timber structures. Nondestructive evaluation (NDE) methods can play an important role in the in-situ assessment of structural performance. The ultrasonic technique has been found to be more accurate than the conventional practice of visual inspection in assessing the defects such as decays, knots, and splits in wood [1]
