Dynamic Photoelasticity as an Aid to Sizing Surface Cracks by Frequency Analysisze surface cracks. Most use compressional (P) and shear (S) waves. Less attention has been given to using Rayleigh (R) waves or surface waves for sizing cracks. Since the energy of Rayleigh waves is confined to a layer of material near the surface, these waves have à great potential for sizing surfa

Influence of Initial Defect Distribution on the Life of the Cold Leg Piping Systemvides for fatigue resistance by avoiding the initiation of cracks, whereas the second, damage tolerance, presumes the existance of cracks and defects and guards against their unstable growth. This paper examines the utility of these approaches in the context of the sensitivity of piping system life

In-Flight Acoustic Emission Monitoringck in a critical structural member. It has been demonstrated that valid AE can be collected even in this hostile environment. Spurious data from background noise have been eliminated using a suitable frequency bandpass and a zone-isolation technique. A linear correlation between valid AE and increas
