“…Lamb wave interactions with damage in metallic and composite materials have also found little attention. Examples in metallic structures include elastic wave interactions with various crack configurations using the MSLM approach [29], Lamb wave interactions with a hole in plates using the FE analysis [30], Lamb wave interactions with surface defects in plates using a combined FE and modal expansion method [31] and Lamb wave propagation analysis in circular pipes with slots using the FE analysis [32].…”

Lamb waves have shown great potential for structural health monitoring. The technique is based on guided ultrasonic waves introduced into a structure at one point and sensed at a different location. Damage in a structure is identified by a change in the output signal. However, previous studies show that even simple structural configurations can lead to complex response signals. Therefore a knowledge and understanding of wave propagation can ease the interpretation of damage detection results. This paper reports an application of the local interaction simulation approach for Lamb wave propagation modelling in metallic structures. The focus of the analysis is on two-dimensional wave interactions with slot-type defects. The method shows the potential for complex modelling of acousto-ultrasonic waves in damage detection applications.

“…Implicit analysis can solve nonlinear problems due to convergent solutions for each state received through iteration. Explicit analysis is usually used for problems of linear wave propagation along a structure as every kinematical state is calculated through the previous state [1,86,127,128,129,130,131]. For models including phased array sensors, force loadings can be used instead of displacement loadings.…”

“…Industrial pipeline systems are commonly used to transport oil, gas and petrochemical products (e.g., corrosive substances). In-service inspection is required to avoid catastrophic failures and to guarantee the safe operation of pipelines [1,2,3,4,5]. A defect is considered an elementary form of failure in pipes that could fail a safety system [4].…”

This paper aims to provide an overview of the experimental and simulation works focused on the detection, localisation and assessment of various defects in pipes by applying fast-screening guided ultrasonic wave techniques that have been used in the oil and gas industries over the past 20 years. Major emphasis is placed on limitations, capabilities, defect detection in coated buried pipes under pressure and corrosion monitoring using different commercial guided wave (GW) systems, approaches to simulation techniques such as the finite element method (FEM), wave mode selection, excitation and collection, GW attenuation, signal processing and different types of GW transducers. The effects of defect parameters on reflection coefficients are also discussed in terms of different simulation studies and experimental verifications.

Wave propagation modelling is important for reliable damage detection based on Lamb waves. A number of different numerical computational techniques have been developed for wave propagation studies. The local interaction simulation approach, used for modelling sharp interfaces and discontinuities in complex media, has been applied effectively for numerical simulations of elastic wave interaction with structural damage. The paper builds upon this experience and reports numerical investigations of Lamb wave propagation modelling for damage detection in metallic structures. The ultimate objective of the investigations is to demonstrate that numerical simulations can significantly ease the monitoring strategy used for damage detection with Lamb waves. The interaction of fundamental Lamb wave modes with a rectangular damage slot in an aluminium plate is investigated as an example. For the sake of completeness, the first part of the paper forms an introduction to wave propagation studies for damage detection. The local interaction simulation approach is implemented. This is followed by a series of two-dimensional studies of wave interaction with damage.
