Time-Harmonic Elastic-Wave Scattering: The Role of Hypersingular Boundary Integral Equations
Conference paper
Summary
Some numerical data for scattering of elastic waves from cracks are presented using a hypersingular boundary integral formula. Then it is shown how the appropriate hypersingular formulas, needed for a formulation for elastodynamic scattering from any void shape, valid at all frequencies, may be derived from the hypersingular formula for cracks.
