Nonlinear postbuckling of eccentrically stiffened functionally graded plates and shallow shells
Tập 33 Số 3 - 2011
Dao Huy Bich, Nguyen Thi Phuong, Vu Hoai Nam
The paper deals with the formulation of governing equations of eccentrically
stiffened functionally graded plates and shallow shells based upon the classical
shell theory and the smeared stiffeners technique taking into account
geometrical nonlinearity in Von Karman-Donnell sense. Material properties are
assumed to be temperature-independent and graded in the thickness direction
according to a sim... hiện toàn bộ

Free vibration of functionally graded sandwich plates with stiffeners based on the third-order shear deformation theory
Tập 38 Số 2 - 2016
Do Van Thom, Pham Tien Dat, Doan Trac Luat
In this paper, the free vibration of functionally sandwich grades plates with
stiffeners is investigated by using the finite element method. The material
properties are assumed to be graded in the thickness direction by a power-law
distribution. Based on the third-order shear deformation theory, the governing
equations of motion are derived from the Hamilton's principle. A parametric
study is... hiện toàn bộ

Duality in the analysis of responses to nonlinear systems
Tập 32 Số 4 - 2010
Nguyen Dong Anh
The paper provides a new view on the averaging procedure and equivalent
linearization in the study of nonlinear mechanics. It is shown that the duality
of those techniques can be used to obtain better approximate solutions or to
separate the original nonlinear systems subjected to periodic and random
excitations into deterministic and stochastic ones.
An edge-based smoothed finite element for buckling analysis of functionally graded material variable-thickness plates
Tập 43 Số 3 - 2021
Tran The Van, Pham Quoc Hoa, Tran Van Ke, Nguyen Thoi Trung, Tran Trung Thanh
The paper aims to extend the ES-MITC3 element, which is an integration of the
edge-based smoothed finite element method (ES-FEM) with the mixed interpolation
of tensorial components technique for the three-node triangular element (MITC3
element), for the buckling analysis of the FGM variable-thickness plates
subjected to mechanical loads. The proposed ES-MITC3 element is performed to
eliminate the... hiện toàn bộ

Finite element analysis of laminated composite plates using high order shear deformation theory
Tập 29 Số 1 - 2007
Tran Ich Thinh, Ngo Nhu Khoa
A rectangular non-conforming element based on Reddy's higher-order
shear deformation plate theory is developed. Although the plate theory is quite
attractive but it could not be exploited as expected in finite-element analysis.
This is due to the difficulties associated with satisfaction of inter-elemental
continuity requirement and satisfy zero shear stress boundary conditions of the
plate theory... hiện toàn bộ

Dispersion equation of Rayleigh waves in transversely isotropic nonlocal piezoelastic solids half-space
Tập 41 Số 4 - 2019
Do Xuan Tung
This study is devoted to investigate the propagation of Rayleigh-type waves in
transversely isotropic nonlocal piezoelastic half-space. When the stress-free
boundary is maintained at charge-free condition, the dispersion equation for the
propagation of Rayleigh waves at the free surface of transversely isotropic
piezoelastic solids has been obtained. Based on the obtained dispersion
equation, the... hiện toàn bộ

Non-linear dynamical analysis of imperfect functionally graded material shallow shells
Tập 32 Số 1 - 2010
Vu Do Long, Dao Huy Bich
Dynamical behaviors of functionally graded material shallow shells with
geometrical imperfections are studied in this paper. The material properties are
graded in the thickness direction according to the power-law distribution in
terms of volume fractions of the constituents of the material. The motion,
stability and compatibility equations of these structures are derived using the
classical shell... hiện toàn bộ
