dc.description.abstract <p>Using the T-Matrix or Null Field method elastic wave scattering from the following geometries have been studied (a) Rotationally symmetric configurations consisting of two spheroidal cavities separated by a finite distance and with different eccentricities. Exact calculations are compared with single scattering approximations. The frequency spectra are interpreted for various scattering geometries and compared with experiments. The effect of change in distance between the scatterers is also discussed. (b) Scattering from rotationally symmetric cavities with odd shapes like "Pinnochio", Rockwell Science Center sample #73 and "Micky Mouse", Rockwell Science Center sample #70 was also studied and compared with numerical results using other techniques as well as experiments. Several ways of studying such problems is also discussed. (c) A numerical technique is proposed to study dynamic stress concentrations.</p>
