There are various health issues associated with the different stages of long-distance
pipeline transportation. These issues pose potential risks to environmental pollution …

An axisymmetric guided wave mode is excited independently within a circular tube structure
to reduce the complexity of signal interpretation through the prevention of unwanted wave …

Guided wave inspection is a commonly used technique in structural health monitoring, yet
there are challenges associated with ultrasonic inspection of polymeric structures due to …

Localizing defects in long-range pipelines is essential to reduce the inspection time and
develop timely repair strategies. The acoustic emission (AE) method is employed to pinpoint …

Metamaterials are composite and artificial materials with extraordinary effective properties
that existing bulk materials do not exhibit. Acoustic metamaterials and phononic crystals are …

The conventional method for one-dimensional acoustic emission (AE) source localization
relies on two sensors to calculate the time-of-flight (TOF) and subsequently determine the …

Mechanical waves enable energy transport through the oscillation or vibration of particles
within their propagation medium. They are essential in many applications that impact our …

Abstract Guided Wave Ultrasonics and Acoustic Emission are two common Nondestructive
Evaluation (NDE) methods, which are based on propagating elastic waves in solids. Current …

This paper discusses challenges, limitations and problems arising in currently employed
acoustic emission testing systems, sensors and signal processing algorithms. Main factors …

Pipelines are vital elements in the oil and gas infrastructure, and damage to them can have
serious consequences. This article aims to determine or study the basic concepts of acoustic …
