A Baseline and Vision of Ultrasonic Guided Wave Inspection Potential
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultrasonic guided wave inspection is expanding rapidly to many different areas of manufacturing and in-service inspection. The purpose of this paper is to provide a vision of ultrasonic guided ...
Special Issue on the Nondestructive Evaluation of Pipeline and Vessel Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This special issue of the journal is dedicated to some contemporary aspects of nondestructive evaluation applied to pipeline and vessel structures. This critical area of research, development, ...
Flexural Torsional Guided Wave Mechanics and Focusing in Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Theoretical work on flexural torsional guided waves in pipe is presented along with angular profile experimental justification. Combined with previous work on flexural longitudinal modes and ...
Surface Waves for Material Characterization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Analyses are presented for the propagation of harmonic surface waves on a transversely isotropic layer rigidly bonded to a transversely isotropic substrate of different material. The layer-substrate ...
A Guided Wave Plate Experiment for a Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The plate approximation of a pipe is a topic discussed for decades. Rules have been established to make the comparisons. Presented here is a related topic, but one to answer the question of ...
High Frequency Guided Wave Natural Focusing Pipe Inspection With Frequency and Angle Tuning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When ultrasonic guided wave nondestructive evaluation is used to inspect pipelines, partial loading of transducers around the circumference leads to a non-axisymmetric energy distribution. At ...
Guided Wave Focusing Mechanics in Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Guided waves can be used in pipe inspection over long distances. Presented in this paper is a beam focusing technique to improve the S∕N ratio of the reflection from a tiny defect. Focusing ...
Guided Wave Propagation Mechanics Across a Pipe Elbow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wave propagation across a pipe elbow region is complex. Subsequent reflected and transmitted waves are largely deformed due to mode conversions at the elbow. This prevents us to date from ...
Guided Wave Resonance Tuning for Pipe Inspection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tremendous interest has surfaced recently on the use of guided waves in pipe inspection in the oil, chemical, and power generating industries. Relatively long lengths of piping can be inspected ...
A Natural Focusing Low Frequency Guided Wave Experiment for the Detection of Defects Beyond Elbows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Long range ultrasonic guided wave inspection is advancing rapidly and is quite commonplace today. Benefits of using longitudinal or torsional modes are being established in special circumstances ...
