Prediction of shear strength of corrosion reinforced concrete beams using Artificial Neural Network - 2022
Panagiotis G. Asteris, Thuy-Anh Nguyen
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... hiện toàn bộ

Nonlinear buckling and postbuckling of spiral stiffened FG-GPLRC cylindrical shells subjected to torsional loads - 2021
Kha Hoa Le, Tho Hung Vu, Hong Quan Pham, Hoai Nam Vu
The nonlinear buckling behavior of functionally graded graphene platelet
reinforced composite (FG-GPLRC) cylindrical shells reinforced by ring, stringer
and/or spiral FG-GPLRC stiffeners under torsional loads is studied by an
analytical approach. The governing equations are based on the Donnell shell
theory with geometrical nonlinearity of von Kármán-Donnell-type, combining the
improvability of Le... hiện toàn bộ

Nguyen Thi Phuong, Cao Van Doan, Vu Hoai Nam
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 compressive strength of concrete at high heating conditions by using artificial neural network-based Bayesian regularization Tập 2 Số 1 - Trang 9-21 - 2022
Marijana Hadzima-Nyarko, Son Hoang Trinh
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... hiện toàn bộ

Temperature effect on the characteristic quantities of microstructure and phase transition of the alloy Ag0.25Au0.75 - 2023
Ștefan Țălu , Tuan Quoc Tran, Hoang Van Ong, Ha Thi Vu, Duyen Thi Tran, Thu-Cuc Thi Nguyen
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 ... hiện toàn bộ

Nguyen Thi Phuong, Vu Minh Duc, Luu Ngoc Quang
The nonlinear dynamic buckling responses of functionally graded graphene
platelet reinforced composite (FG-GPLRC) cylindrical and sinusoid panels with
porous core are presented in this paper. The governing formulations are
established by applying the nonlinear higher-order shear deformation theory
(HSDT). an approximation technique is used to determine the stress function for
complexly curved pane... hiện toàn bộ
