Non-destructive ultrasonic inspection is an effective technique to ensure structural integrity of steel bridges. Quantitative information on flaw size, location and orientation is required for cost-effective maintenance of bridge components by implem

The reflection and transmission of a plane time-harmonic surface wave which is obliquely incident on the edge of a quarter space is investigated theoretically, numerically, and experimentally. The theoretical formulation of the problem, which takes a

A configuration of transducers together with a self-calibrating measurement technique is proposed to investigate the reflection and transmission of surface waves by a surface-breaking or near surface defect. By means of this technique, the ratio of t

A technique is described for simultaneous velocity and attenuation measurements in the monitoring of material properties. To determine the attenuation, the amplitudes of tone-burst signals generated over a wide frequency range have been measured. For

An ultrasonic technique has been developed to characterize fatigue cracks in the internal layers of multi-layer aircraft structures. The technique is based on the B-scan image acquisition and processing to obtain quantitative information on crack cha

This paper will address the integration of several NDE techniques that are used for the inspection of aircraft structures. The concept of a modular inspection system with interchangeable components will be presented. The modular concept provides grea

Thin-walled multi-layered structures, with sealants in-between the layers, may develop interface defects on deeper interfaces. For nondestructive inspection it is desirable to generate a visual indication of such defects by an ultrasonic imaging tech

When a surface containing a surface-breaking crack is directly accessible for the generation of ultrasound, the use of surface waves is a preferred technique for depth determination of the crack. In principle, the crack depth can be determined by an
