Ultrasonic modeling and experiments: An industrial case: Bimetallic weld in nuclear power plant

Ultrasonic three-dimensional probe modeling in anisotropic solids

“…Fellinger et al 10 use the elastodynamic finite integration technique ͑EFIT͒ to solve mainly 2-D wave propagation in various materials containing defects. Wave propagation through a bimetallic weld is studied by Minachi et al 11 and Nouailhas et al 12 Minachi et al 11 study beam propagation and compare the Gauss-Hermite beam model and a finite element method. Nouailhas et al 12 compare a ray tracing code and a finite element code and use various experiments to validate the codes.…”

Nouailhas et al 12 compare a ray tracing code and a finite element code and use various experiments to validate the codes. In both of these last two papers, the computations are performed in 2D.…”

Three-Dimensional Ultrasonic Crack Detection in Anisotropic Materials

“…Their incident field is generated by a three-dimensional probe model of P-, SV-, or SH-type. Examples of other works in the area of wave propagation in anisotropic solids are Spies and Kröning [19], Spies [18], Lord et al [7], Minachi et al [11], Nouailhas et al [14], and Ogilvy [15]. Some models including anisotropic materials are by, e.g., Mattsson and Niklasson [10], Rajapakse and Gross [16], Fellinger et al [5], and Klaholz et al [6].…”

“…Rajapakse and Gross also consider two-dimensional scattering but in-plane instead of anti-plane. Minachi et al [11] and Nouailhas et al [14] study wave propagation through a bimetallic weld. Fellinger et al use the elastodynamic finite integration technique (EFIT) to study wave propagation and scattering in anisotropic solids.…”

Ultrasonic beam propagation through a bimetallic weld — a comparison of predictions of the Gauss-Hermite beam model and finite element method

“…Two of the existing models used for the simulation of elastic wave propagation are the finite difference and finite element methods [1][2]. These methods have good accuracy and can be applied to wide variety of geometrical and material conditions.…”
