Nondestructive evaluation of thick-section composites and sandwich structures: A review
M. E. Ibrahim,M. E. Ibrahim +1 more
TL;DR: In this article, a review of advances reported in the NDE of thick-section composites (structures of thickness above 15 mm are considered for the purposes of this review), and identifies future research opportunities to overcome the limitations of existing technologies.
Application and comparison of three tomographic techniques for detection of decay in trees
TL;DR: In this article, the application of electric, ultrasonic and georadar tomography for detection of decay in trees and their comparison with the traditional penetrometer is also evaluated, critically considering some "open problems".
Journal ArticleDOI
Methods for measuring stiffness of young trees
TL;DR: In this article, a number of approaches that could be used as a selection tool in tree breeding for better product performance of radiata lumber were explored. But the results do not offer definitive solutions but explores a good correlation between acoustic and static measurements of modulus of elasticity.
