In this paper, the bending behavior of rectangular plates with stepped thickness resting on an elastic half-space foundation is investigated through analytic method. Combined theory thin and moderately thick plate, plate divided into upper lower plates, Fourier series used to obtain analytical solution deflection interaction force between foundation. The influence modulus theory, dimension also...

This paper presents a windowed Green function (WGF) method for the numerical solution of problems elastic scattering by "locally-rough surfaces" (i.e., local perturbations half space), under either Dirichlet or Neumann boundary conditions, and in both two three spatial dimensions. The proposed WGF relies on an integral-equation formulation based free-space function, together with smooth operato...
