Study on Stability of Elastic Compression Bending Bar in Viscoelastic Medium

open access: yesApplied Sciences, 2023
In the southeastern coastal regions of China, thick layers of marine soft soil are widely distributed, exhibiting characteristics such as high compressibility, high porosity, low strength, high sensitivity, and easy thixotropy, and these viscoelastic ...

Quantum Structures: An Attempt to Explain the Origin of their Appearance in Nature [PDF]

open access: yes, 1995
We explain the quantum structure as due to the presence of two effects, (a) a real change of state of the entity under influence of the measurement and, (b) a lack of knowledge about a deeper deterministic reality of the measurement process. We present a

Effect of Soil Nonlinearity on Analysis of Raft Foundation

open access: yesCivil and Environmental Engineering, 2022
Soil supporting foundations behave in a nonlinear manner at loading close to its bearing capacity. This behavior affects soil pressure distribution and the corresponding stresses in the raft foundation, which differs significantly from considering the ...

Self-gravitating elastic bodies [PDF]

open access: yes, 2014
Extended objects in GR are often modelled using distributional solutions of the Einstein equations with point-like sources, or as the limit of infinitesimally small "test" objects.

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.

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 ...

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.
