“…Let us consider wave excitation in the wedge by the rectangular piezoelectric actuator with an intermediate laminated rectangular EMM block as schematically shown by a dashed circle in Figure 1 . In the present study, we employ the boundary integral equation method [ 29 , 32 , 33 ], the semi-analytical hybrid approach [ 34 , 35 ] and the finite element method to solve the boundary-value problem described in the following subsection.…”

“…Wave motion of a piezoelectric transducer with given voltage on surface electrodes is simulated using the spectral finite element method. Wave-field in the layered waveguide with regular boundaries is obtained in the integral form using the Fourier transform of the Green’s matrix of the layered structure and a load generated by the transducer [ 34 , 35 ]. The employed numerical algorithm for the evaluation of the Green’s matrix of layered elastic structures including periodic ones can be found in [ 33 , 46 ].…”

“…Current nondestructive testing technologies for grouting sleeves include impact echo, ray detection, embedded chip, and infrared thermal imaging methods, each with its limitations [6][7][8][9]. Although the impact echo method [10,11] has low cost and simple operation, its accuracy is insufficient.…”

“…Complex engineering problems currently can be solved using robust numerical methods such as the finite element method, as well as the spectral element method, the boundary element method, the finite volume method, and meshless methods. Various coupling procedures (hybrid and coupled numerical methods) have been proposed incorporating different numerical methods in order to take advantage of their respective benefits [1][2][3].…”
