Magnetohydrodynamic natural convection in a vertical cylindrical cavity with sinusoidal upper wall temperature
(2009)
A series of numerical simulations were performed in order to study liquid metal MHD natural convection in a vertical cylindrical container with a sinusoidal temperature distribution at the upper wall and the other surfaces ...
Constitutive modeling of porous viscoelastic materials
(2007)
The effect of porosity on the constitutive response of an isotropic linearly viscoelastic solid that obeys a constitutive law of the standard differential form is investigated under small strain deformation conditions. The ...
Antiplane deformation of a partially bonded elliptical inclusion
(1997)
A new method that introduces two holomorphic potential functions (the two-phase potentials) is applied to analyze the antiplane deformation of an elliptical inhomogeneity partially-bonded to an infinite matrix. Elastic ...
Spherical capsules in three-dimensional unbounded Stokes flows: effect of the membrane constitutive law and onset of buckling
(2004)
The dynamic response of an initially spherical capsule subject to different externally imposed flows is examined. The neo-Hookcan and Skalak et al. (Biophys. J., vol. 13 (1973), pp. 245-264) constitutive laws are used for ...
TRANSIENT LAMINAR MHD NATURAL CONVECTION COOLING IN A VERTICAL CYLINDER
(2012)
A numerical study is presented of transient laminar natural convection cooling of an electrically conductive fluid, placed in a vertical cylinder in the presence of an axial magnetic field. The cylindrical wall is suddenly ...
Stability of confined thin-walled steel cylinders under external pressure
(2009)
The present paper investigates the structural stability of thin-walled steel cylinders surrounded by an elastic medium, subjected to uniform external pressure. A two-dimensional model is developed, assuming no variation ...
Mechanical behavior and wrinkling of lined pipes
(2012)
The paper focuses on wrinkling of lined pipes (sometimes referred to as clad pipes) under bending loading, where a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The problem is solved ...
Bubble rise dynamics in a viscoplastic material
(2015)
The axisymmetric dynamics of a bubble rising in a Bingham fluid under the action of buoyancy is studied. The Volume-of-Fluid (VOF) method is used to solve the equations of mass and momentum conservation, coupled to an ...
Modelling the Environmental Effects of Railway Vibrations from Different Types of Rolling Stock: A Numerical Study
(2015)
This paper analyses the influence of rolling stock dynamics on ground-borne vibration levels. Four vehicle types (Thalys, German ICE, Eurostar, and Belgian freight trains) are investigated using a multibody approach. First, ...
Evaluation of material properties of incompressible hyperelastic materials based on instrumented indentation of an equal-biaxial prestretched substrate
(2015)
It is well known that instrumented indentation tests are useful tools in probing mechanical properties of materials such as metals and ceramics. Instrumented indentation of hyperelastic materials such as rubbers, bio-materials, ...
