A new analytic symplectic elasticityapproach for beams resting on Pasternak elastic foundations [PDF]
Journal of Mechanics of Materials and Structures, 2010 Analytic solutions describing the stresses and displacements of beams on a Pasternak elastic foundation are presented using a symplectic method based on classical two-dimensional elasticity theory. Hamilton’s principle with a Legendre transformation is employed to derive the Hamiltonian dual equation, and separation of variables reduces the dual ...

Buckling Analysis of a Nanowire Lying on Winkler–Pasternak Elastic Foundation
Mechanics of Advanced Materials and Structures, 2014 This article studies the axial buckling of a nanowire (NW) lying on Winkler–Pasternak substrate medium with the Timoshenko beam theory. The surface effect of the NW is accounted for with the Steigmann–Ogden model. An explicit solution of the critical buckling force and its associated buckling mode are obtained analytically.

Response of an Elastic Plate on a Pasternak Foundation to a Moving Load
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1980 This paper considers the response of an elastic plate to a moving load. The plate is resting on a Pasternak foundation and the load moves uniformly with a constant velocity. The deflection of the plate is expressed in the form of integration. Combinations of the velocity and the foundation parameters yield the expression in five types of integration ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology
Deep Underground Science and Engineering, EarlyView.This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...
