Vibration fatigue occurs easily in offshore platform pipelines that have been in service for
several years. Timely damage detection and the detection of fatigue cracks are of great …

The acoustic emission signals collected by oil and gas pipelines on offshore platforms are
disturbed by noise, which makes it difficult to locate the pipeline damage. To solve this …

The analysis of acoustic signals to localize acoustic emission (AE) sources has emerged as
a kind of favored approach. Despite recent advances, the task of localizing AE sources such …

In this work the features of the propagation of the acoustic waves in the matrix sample
(DERAKANE 411-350 epoxy vinyl ester resin) by the source pencil lead break (PLB) with …

Abstract Long-distance, large-diameter, and high-pressure pipelines represent the future of
oil and gas pipeline construction. X90 pipeline steel is expected to become the standard …

Composites play an important role in the development of modern science and technology,
but the special anisotropy leads to difficulties in impact localization. To achieve impact …

Fiber-optic sensors have several features that determine the effectiveness of their use for
diagnostics of polymer composite materials (PCM). These features include the tolerance of …

This paper presents the results from conducting a series of experiments with a Hsu-Nielsen
Source, accompanied by corresponding numerical simulations on a solid block. The aim …

This paper presents the results of the analysis of acoustic emission signals (AE) recorded
during the propagation of sound waves in rock samples. The sources are excited by …

Acoustic Emission (AE) testing is a non-destructive evaluation technique that has gained
significant attention in pipeline monitoring. Pencil-lead breaks (PLBs) are commonly used in …
