Stress analysis of thin and thick plates on elastic foundations using boundary and finite element methods [PDF]

open access: yes, 1991
In this work an attempt has been made to derive a full finite element and boundary element theory for the analysis of thin and thick plates on elastic foundations. A new high order shear finite element capable of the analysis of thin thick plates has

Wigner functions with boundaries [PDF]

open access: yesJournal of Mathematical Physics, 2002
We consider the general Wigner function for a particle confined to a finite interval and subject to Dirichlet boundary conditions. We derive the boundary corrections to the “stargenvalue” equation and to the time evolution equation. These corrections can be cast in the form of a boundary potential contributing to the total Hamiltonian which together ...

Boundary functions for bounded harmonic functions [PDF]

open access: yesTransactions of the American Mathematical Society, 1969
Let D be the open unit disk in the complex plane and let C be its boundary, the unit circle. If 4 E C, then by an arc at t we mean a simple arc y with one endpoint at 4 such that y { } ( D. In this paper we use the term boundazy function in the following sense.

Modified Green's Functions for Shallow Water Acoustic Wave Propagation [PDF]

open access: yes, 2004
This article presents an assessment of alternative forms of the Green’s function for boundary element simulations of acoustic wave propagation in shallow water. It is assumed that the problem is two-dimensional, the source of acoustic disturbance is time-

Representation of Green’s functions of the wave equation on a segment in finite terms [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2022
Solutions of initial-boundary value problems on the excitation of oscillations of a finite segment by an instantaneous point sourse are investigated. Solutions to these problems, called Green's functions of the equation of oscillations on a segment ...
