A DIFFERENTIAL QUADRATURE FINITE ELEMENT METHOD
Tập 02 Số 01 - Trang 207-227 - 2010
This paper studies the differential quadrature finite element method (DQFEM)
systematically, as a combination of differential quadrature method (DQM) and
standard finite element method (FEM), and formulates one- to three-dimensional
(1-D to 3-D) element matrices of DQFEM. It is shown that the mass matrices of C
0 finite element in DQFEM are diagonal, which can reduce the computational cost
for dyn...
Visco-Elastic Analysis on the Effect of Flexible Layer on Mechanical Behavior of Tunnels
Tập 11 Số 03 - Trang 1950027 - 2019
Installing flexible layer is one kind of supporting techniques to deal with the
large deformation in tunnels excavated in viscoelastic rocks. The role of
flexible layer is to absorb rock deformation due to rock rheology. For further
understanding the effect of flexible layer on mechanical behavior of tunnels, a
three-layered model is established to study the mechanical behavior of tunnel
where fle...
Wave Finite Element Method Based on Reduced Model for One-Dimensional Periodic Structures
Tập 07 Số 02 - Trang 1550018 - 2015
In this paper, an efficient numerical approach is proposed to study free and
forced vibration of complex one-dimensional (1D) periodic structures. The
proposed method combines the advantages of component mode synthesis (CMS) and
wave finite element method. It exploits the periodicity of the structure since
only one unit cell is modelled. The model reduction based on CMS improves the
computational ...
Nonlinear Thermo-Mechanical Stability Analysis of Eccentrically Spiral Stiffened Sandwich Functionally Graded Cylindrical Shells Subjected to External Pressure
Tập 11 Số 05 - Trang 1950045 - 2019
A new analytical approach to investigate the nonlinear buckling and postbuckling
of the sandwich functionally graded circular cylindrical shells reinforced by
ring and stringer or spiral stiffeners subjected to external pressure is
presented in this paper. By employing the Donnell shell theory, the geometrical
nonlinearity in Von Kármán sense and developed Lekhnitskii’s smeared stiffener
technique...
Three-Dimensional Passive and Active Control Methods of Shock Wave Train Physics in a Duct
Tập 08 Số 04 - Trang 1650047 - 2016
In the present work, the physics of a three-dimensional shock train in a
convergent-divergent nozzle is numerically investigated. In this regards, the
Ansys-Fluent Software with Algebraic Wall-Modeled Large-Eddy Simulation (WMLES)
is used. To estimate precision and errors accumulation we used the Smirinov’s
method; fine flow structures are obtained via Laplacian of density called
shadowgraph and t...
High Strain Rate Behavior of Epoxy Graphene Oxide Nanocomposites
Tập 10 Số 07 - Trang 1850072 - 2018
The present work investigates the novel impact loading response of
two-dimensional graphene oxide (GO) reinforced epoxy nanocomposites at high
strain rate. The testing was performed up to 1000[Formula: see text]s[Formula:
see text] of high strain rate, where maximum damage occurs during the impact
loading conditions. The Split Hopkinson Pressure Bar (SHPB) was used for the
impact loading of the co...
EFFECTS OF BALLOON LENGTH AND COMPLIANCE ON VASCULAR STENT EXPANSION
Tập 02 Số 03 - Trang 681-697 - 2010
Vascular stents are used to dilate arteries that are narrowed or clogged by
plaque. However, in-stent restenosis is still one of the major causes of the
clinical failure. It is believed that vessel trauma imposed during stent
deployment is closely correlated to restenosis. Clinical observations show that
the longitudinal and axial geographic miss in pre/post-dilation are responsible
for the vessel...
ON THE SIMULATION OF UNIAXIAL, COMPRESSIVE BEHAVIOR OF AMORPHOUS, GLASSY POLYMERS WITH MOLECULAR DYNAMICS
Tập 02 Số 03 - Trang 515-541 - 2010
Molecular dynamics (MD) simulations offer an interesting route to simulating
deformation and fracture behavior of amorphous glassy polymers. However, MD
simulations are performed at extremely high rates and on very small samples
(though periodic boundary conditions are routinely used) containing at most
hundreds of chains which are much shorter than in real life. In this work, we
try to assess the...
An Accurate and Efficient Method for Dynamic Analysis of Two-Dimensional Periodic Structures
Tập 08 Số 02 - Trang 1650013 - 2016
In this paper, an accurate and efficient method is presented for analyzing the
dynamic response of two-dimensional (2D) periodic structures. The algebraic
structure of the corresponding matrix exponential is analyzed and, based on its
special structure, an accurate and efficient method for its computation is
proposed. Accuracy is maintained using the precise integration method (PIM), and
great eff...
A Novel Analytical Approach for Nonlinear Thermo-Mechanical Buckling of Higher-Order Shear Deformable Porous Circular Plates and Spherical Caps with FGM Face Sheets
Tập 15 Số 05 - 2023
A novel analytical approach for nonlinear thermo-mechanical buckling of
higher-order shear deformable porous circular plates and spherical caps with
functionally graded material (FGM) face sheets resting on Pasternak elastic
foundation is presented in this paper. The circular plates and spherical caps
are assumed to be subjected to uniformly distributed external pressure and/or
uniformly distribut...
