Analysis of segregated boundary-domain integral equations for mixed variable-coefficient BVPs in exterior domains

This is the post-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2011 Birkhäuser Boston.Some direct segregated systems of boundary–domain integral equations (LBDIEs) associated with the mixed boundary value problems for scalar PDEs with variable coefficients in exterior domains are formulated and analyzed in the paper. The LBDIE equivalence to the original boundary value problems and the invertibility of the corresponding boundary–domain integral operators are proved in weighted Sobolev spaces suitable for exterior domains. This extends the results obtained by the authors for interior domains in non-weighted Sobolev spaces.The work was supported by the grant EP/H020497/1 ”Mathematical analysis of localised boundary-domain integral equations for BVPs with variable coefficients” of the EPSRC, UK

Combined displacement-traction boundary value problems for elastic plates

The solvability is investigated of the equations of bending of plates when either the first two displacement components and the transverse shear force or the bending and twisting moments and the deflection are prescribed on the boundary of the middle section domain. These problems are then reduced to boundary integral equations, whose solutions are sought in spaces of distributions

Dynamic transmission problems for plates

The existence of distributional solutions is investigated for the boundary intergral equations associated with the bending of a thin elastic plate in the dynamic contact problem

The Solvability of boundary integral equations for the Dirichlet and Neumann problems in the theory of thin elastic plates

The existence, uniqueness, and continuous dependence on the data are investigated for the weak solutions of boundary integral equations arising in the interior and exterior Dirichlet and Neumann problems for plates with transverse shear deformation treated by means of potential methods
