Dislocation theory as a 3-dimensional translation gauge theory [PDF]

open access: yes, 1999
We consider the static elastoplastic theory of dislocations in an elastoplastic material. We use a Yang-Mills type Lagrangian (the teleparallel equivalent of Hilbert-Einstein Lagrangian) and some Lagrangians with anisotropic constitutive laws.

Thick Orthotropic Rectangular Plates on Elastic Foundations

open access: yesTikrit Journal of Engineering Sciences, 2007
In this research, Mindlin’s thick plate theory is extended to include orthotropic plates under the effects of externally distributed moments and shearing forces at top and bottom faces of the plate. These shearing forces produce in-plane forces in plates

Quasi 3-D trigonometric plate theory for bending analysis of EG plates resting on Pasternak foundations

open access: yesCurved and Layered Structures, 2018
This paper deals with the bending analysis of exponentially graded material (EGM) plates resting on two-parameter elastic foundations according to a trigonometric shear deformation plate theory (TPT) using Navier’s technique.

Geotechnical design with apparent seismic safety factors well-bellow 1 [PDF]

open access: yes, 2014
The paper demonstrates that whereas often in seismic geotechnical design it is not realistically feasible to design with ample factor of safety against failure as is done in static design, an "engineering" apparent seismic factor of safety less than 1 ...

Nonlinear post-buckling of thin FGM annular spherical shells under mechanical loads and resting on elastic foundations

open access: yesVietnam Journal of Mechanics, 2014
This paper presents an analytical approach to investigate the nonlinear buckling and post-buckling of thin annular spherical shells made of functionally graded materials (FGM) and subjected to mechanical load and resting on Winkler-Pasternak type ...

Stability of Cracked Plates with Nonlinearly Variable Thickness Resting on Elastic Foundations

open access: yesJournal of Materials and Engineering Structures, 2022
In this paper, the stability of rectangular cracked plates with nonlinearly variable thickness resting on the elastic foundations is studied. The thickness of the plate varies exponentially along the x-axis.

On the Microscopic Foundations of Elasticity

open access: yes, 2002
The modeling of the elastic properties of disordered or nanoscale solids requires the foundations of the theory of elasticity to be revisited, as one explores scales at which this theory may no longer hold.

Fidelity of computational modelling of offshore jacket platforms [PDF]

open access: yes, 2019
The development of oil and gas exploitation offshore has a history of about half a century. Many platforms have been built since to facilitate the production of hydrocarbons oil and gas, of which fixed offshore jacket type structures are the most ...
