“…Moreover, for the case of laser irradiating film-substrate systems, Coulette et al 60 study the transient mechanical displacement at the epicenter in two-layer plates by using a two dimensional semi-analytical model. Murray et al 61 investigate the surface acoustic waves (SAWs), using a two-dimensional analytical model, based on temporal Laplace and spatial two dimensional Fourier transformations and assuming the substrate is semi-infinite and laser irradiation is dealt as a surface force source.…”

A review study of the developments in the field of pulsed laser-solid interaction simulation methods, for moderate laser energies, is presented. The paper is focused on the methods that numerically simulate the interactions of pulsed ns-laser with solid metal targets. Three main regimes for pulsed laser excitation, are well established, namely, the thermoelastic, melting and plasma regimes. The modelling and simulation techniques that may numerically describe these three regimes and the occurring dynamic matter responses are reviewed. Modelling efforts concerning various fields of applications of lasers are briefly discussed.

“…Most of theoretical approaches dealing with the generation and propagation of ultrasounds in solids focus on the search of analytical solutions [9][10][11][12][13][14][15]. The numerical approximation achieved by the aid of FEA in such complicated multiphysics problems, provides a convenient tool for the computational study of SAWs.…”

“…Besides classical ultrasonic methods using piezoelectric transducers for the generation and detection of the ultrasonic waves, noncontact laser based ultrasound ͑LBU͒ techniques have also been widely used [1][2][3][4][5][6][7][8][9] for the detection of various kinds of adhesion defects, such as corrosion, 3,4 flaws, 5 disbonds, 6,7 and inclusions. 8 Recently, Weiss and Sigrist described and demonstrated how LBU technique can be used to detect very small delaminations and evaluate their size.…”

Recently it was shown that the pressure wave propagation method, usually used to study electrical behavior of dielectric materials, can be applied to the nondestructive detection and quantitative analysis of adhesion defects in bilayer structures. In this paper, we investigate the possibilities open by the same method to detect and quantify adhesion defects in trilayer structures. After a brief recall of the principle of the method and of the main results obtained for bilayer structures, we describe the trilayer structures to be tested and present preliminary measurements of the acoustical and electrical properties of the materials constituting these samples. Measurements were carried out on kapton ͑52 m͒-adhesive ͑57 m͒-kapton ͑130 m͒ and polyetheretherketone ͑PEEK͒ ͑138 m͒adhesive ͑52 m͒-PEEK ͑138 m͒ transparent samples. The signals are established and analyzed, with the help of simulations, in the cases of structures perfectly bonded, totally disbonded at one interface, and partially disbonded at one or at two interfaces. The excellent agreement between the measurements carried out on perfectly bonded and totally disbonded samples and simulations assesses the correctness of the signal expression for a multilayer structure. By analyzing the signals in the time domain, in a very simple manner, it is possible to determine at which interface the disbonds occur. In the case of partially disbonded structures at one interface, the value of the percentage of totally disbonded area in the tested zone determined by measurements or simulations is very close to that deduced from a photograph of the sample. If the transit time of the pressure pulse in each medium is larger than 11 ns measurements and simulations show that, owing to this method, it is possible to detect and localize in trilayer structures submicron gaps and a percentage of totally disbonded area as low as 10% in the tested zone, which is approximately equal to 30 mm 2 . In the case of partially disbonded samples at the two interfaces, it is possible to make a qualitative analysis of the measurements.
