Numerically Stable form of Green’s Function for a Free-Free Uniform Timoshenko Beam
Mathematics, 2022 Beam models are widely applied in civil engineering, transport, and industry because the beams are basic structural elements. When dealing with the high-order modes of beam in the context of applying the modal analysis method, the numerical instability ...

Interferometric modeling of wave propagation in inhomogeneous elastic media using time reversal and reciprocity [PDF]
, 2006 Time reversal of arbitrary, elastodynamic wavefields in partially open media can be achieved by measuring the wavefield on a surface surrounding the medium and applying the time reverse of those measurements as a boundary condition.

Riquier–Neumann Problem for the Polyharmonic Equation in a Ball
Mathematics, 2023 The Green’s function of the Riquier–Neumann problem for the polyharmonic equation in the unit ball is constructed. Using the obtained Green’s function, an integral representation of the solution to the Riquier–Neumann problem in the unit ball is found.

Green's functions and existence of solutions of nonlinear fractional implicit difference equations with Dirichlet boundary conditions [PDF]
Opuscula MathematicaThis article is devoted to deduce the expression of the Green's function related to a general constant coefficients fractional difference equation coupled to Dirichlet conditions. In this case, due to the points where some of the fractional operators are
