The Effects of Composite Plate Design Parameters on Linear Vibrations by Discrete Singular Convolution Method

Journal of Composite Materials, 2009
This study is devoted to some specific free vibration analysis of thin composite plates based on discrete singular convolution (DSC) approach. As the first analysis, a parametric study is performed on the basis of number of lamination, boundary condition,

Discrete singular convolution for buckling analyses of plates and columns

Structural Engineering and Mechanics, 2008
In the present study, the discrete singular convolution (DSC) method is developed for buckling analysis of columns and thin plates having different geometries. Regularized Shannon?s delta (RSD) kernel is selected as singular convolution to illustrate the present algorithm.

A generalized discrete singular convolution algorithm improved by regularizing singularities for one electron system

Chemical Physics Letters, 2009
A discrete singular convolution (DSC) algorithm was generalized from uniform discretization to nonuniform discretization by introducing a mapping method to regularize the singularities involved. The approach was demonstrated using a radial Schrodinger equation of a hydrogen atom with a Coulomb-like potential that involves a singularity.

Novel Symplectic Discrete Singular Convolution Method for Hamiltonian PDEs

Communications in Computational Physics, 2016
This paper explores the discrete singular convolution method for Hamiltonian PDEs. The differential matrices corresponding to two delta type kernels of the discrete singular convolution are presented analytically, which have the properties of high-order accuracy, bandlimited structure and thus can be excellent candidates for the spatial discretizations

Solving quantum eigenvalue problems by discrete singular convolution

Journal of Physics B: Atomic, Molecular and Optical Physics, 2000
This paper explores the utility of a discrete singular convolution (DSC) algorithm for solving the Schrodinger equation. DSC kernels of Shannon, Dirichlet, modified Dirichlet and de la Vallee Poussin are selected to illustrate the present algorithm for obtaining eigenfunctions and eigenvalues.
