Special Issue on Non-destructive Evaluation

Editorial: Special issue on non-classical mathematics

The 20th century witnessed not only incredible advances in the model theory and proof theory of classical logic, but also a corresponding advance of non-classical (or, as they are also called, non-standard) logics—i.e. the logics that either non-trivially extend, or actually compete with, classical logic of the Aristotelian, Stoic and Boolean tradition. Since the beginning of the 20th century, ...

Marine Composites Non-Destructive Evaluation

An increasing number of marine structures are utilizing composite materials. Major structure and components can be built lighter and corrosion-resistant using composite construction. The recreational boating industry has long recognized this and now commercial ferries are increasingly realizing fuel savings through weight reduction. The US Navy’s DDG-1000 topside structure and LPD-17 advanced e...

Laser-based Non-destructive Evaluation

John S. Popovics Summary Lasers are devices that create a high intensity, directed light beam. The light beam can travel in air or through fiber optic cables. Lasers can be used to generate waves and detect stretching or motion in a solid material without direct contact with the material. Thus lasers are useful in many important engineering applications that require remote non-destructive evalu...

Non-Linear Non-Destructive Evaluation of Concrete

This paper explains non-linear non-destructive evaluation of concrete aimed at examining the occurrence of non-linearity under non-linear wave propagation through the concrete. Standard cubic concrete sections in damaged and undamaged conditions were investigated. The specimen was first damaged under compression testing and then subjected to non-linear ultrasonic evaluation in two directions i....
