【 摘 要 】

A simplified model problem reduced from the general class of elastic scattering problems is analyzed. Both classical Helmholtz and hypersingular formulations are discussed and a general h-p boundary element method based on the Burton-Miller combination of both approaches is formulated. A simple L2-residual a posteriori error estimate is discussed as a basis of adaptive h- or p-refinements.
