Temperature effect on the characteristic quantities of microstructure and phase transition of the alloy Ag0.25Au0.75
Journal of Science and Transport Technology - - 2023
In this research, Molecular Dynamics (MD) simulations were conducted to explore
the temperature effect on the microstructure and phase transition of the
Ag0.25Au0.75 alloy. The findings reveal that as the temperature rises, the
material's phase transition switches from crystalline to liquid and vice versa.
Notably, during the phase transition, significant changes occur in the link
length (r), the ...

Prediction of compressive strength of concrete at high heating conditions by using artificial neural network-based Bayesian regularization
Journal of Science and Transport Technology - Tập 2 Số 1 - Trang 9-21 - 2022
Cement concrete is the most commonly used material today for constructing
residential or commercial buildings, industrial parks, or particular components
such as tunnel slabs where there is a high risk of fire. This structure requires
concrete to be subjected to high temperatures generated by fires. However,
concrete under the influence of high temperature has very complex behavior
states with def...

Buckling behavior of spiral stiffened sandwich FGM cylindrical shells with porous core under axial compression using the FSDT
Journal of Science and Transport Technology - - Trang 1-9 - 2022
The linear buckling behavior of functionally graded cylindrical shells with
porous core stiffened by spiral stiffeners under axial compression using the
first-order shear deformation theory is presented in this paper. The improved
Lekhnitskii’s smeared stiffeners technique is applied for shear deformable
spiral FGM stiffeners. Approximate analytical solutions are assumed to satisfy
the simply supp...

Prediction of California Bearing Ratio (CBR) of Stabilized Expansive Soils with Agricultural and Industrial Waste Using Light Gradient Boosting Machine
Journal of Science and Transport Technology - - 2021
Using agricultural and industrial waste such as bagasse ash, groundnut shell ash
and coal ash in stabilizing expansive soils are used as a subgrade material to
reduce harmful impaction of swelling/shrinkage of expansive soils, reduce
construction costs. It is also a solution for environmental protection.
California Bearing Ratio (CBR) is an important criterion to evaluate the
application technique...

Postbuckling analysis of externally pressured parabola, sinusoidal and cylindrical FG-GRCL panels using HSDT
Journal of Science and Transport Technology - Tập 3 Số 2 - Trang 34-42 - 2023
In the present paper, by using the higher-order shear deformation theory and the
strain-displacement relationships of large deflection, the postbuckling analysis
of the functionally graded graphene-reinforced composite laminated (FG-GRCL)
parabola, sinusoidal, and cylindrical externally pressured panels is presented
in detail. The complex curvature functions of the parabola and sinusoidal panels

Prediction of shear strength of corrosion reinforced concrete beams using Artificial Neural Network
Journal of Science and Transport Technology - - 2022
The shear strength of corroded reinforced concrete (CRC) beams is a critical
consideration during the design stages of RC structures. In this study, we
propose a machine learning technique for estimating the shear strength of CRC
beams across a range of service periods. To do this, we gathered 158 CRC beam
shear tests and used Artificial Neural Network (ANN) to create a forecast model
for the con...
Nonlinear buckling responses of radially pressured FG-GPLRC toroidal shell segments
Journal of Science and Transport Technology - Tập 3 Số 2 - Trang 19-25 - 2023
An analytical approach for nonlinear buckling of functionally graded graphene
platelet reinforced composite toroidal shell segments is presented in this
paper. The Ritz energy procedure is executed, and radial pressure–deflection
expression is constituted to obtain the postbuckling strength and critical
buckling pressure of the shells. Significant influences on the buckling
responses of shells wit...

Nonlinear buckling and postbuckling analysis of cylindrical and sinusoid FG-GPLRC panels under axial compressive load
Journal of Science and Transport Technology - - Trang 44-53 - 2023
This paper presents and analyzes the nonlinear buckling responses of cylindrical
and sinusoid Functionally graded graphene platelet reinforced composite
(FG-GPLRC) panels under axial compressive load. The higher-order shear
deformation theory is applied to establish the governing equations of
structures. The stress function is approximated using the like-Galerkin method,
and the Galerkin method is...
