Pulsed Resonance Identification Method,peripheral waves. The distinguishing feature of this approach is the utilization of short in time (broadband) incident pulse. This ultrasonic method exhibits good capabilities for detection, characterization, and classification of resonances. This approach allows one to reduce the time needed for an

Peripheral Waves in the Scattering by Elastic Cylinders and Spheres, in a liquid are considered. An analysis of the influence of the longitudinal (..) and transverse (..) velocities in the material of the scatterer on the form function and on the properties of the peripheral waves is presented. The form function was calculated in a series form. For its interpretatio

Peripheral Waves in the Scattering by Spherical Shells,erate thickness (with . = 1/32) and from a thick-walled shell (with . = 1/10). The computations have been carried out and analyzed in a broad frequency band (0 ... 400) and for large orders of resonances (.. 100). Attention is focused on the Lamb-type peripheral waves .. and .. (. = 0, 1, 2, 3, 4).

Peripheral Waves in the Scattering of a Plane Acoustic Wave Obliquely Incident on a Solid Elastic Cbeen investigated in detail. The formulation of the problem and its solution in the Rayleigh series form using the eigenfunctions is given in (see Chap. 1). There the form function was computed at various angles of incidence (see Fig. 1.2). In , for the analysis of the peripheral waves
