In this work, ion implantations with in situ transmission electron microscopy observations followed by different rates of temperature ramp were performed in (001)-Si to follow the evolution of He-plates under the influence of hydrogen. The JANNUS and MIAMI facilities were used to study the first stages of growth as well as the interactions between co-planar plates. Results showed that under a l...

The following article investigates buckling of moderately thick circular Nano plates with an orthotropic property under uniform radial compressive in-plane mechanical load. Taking into account nonlocal elasticity theory (Eringen), principle of virtual work, first order shear deformation plate theory (FSDT) and nonlinear Von-Karman strains, the governing equations are obtained based on displacem...

UNLABELLED Trabecular plates and rods are important microarchitectural features in determining mechanical properties of trabecular bone. A complete volumetric decomposition of individual trabecular plates and rods was used to assess the orientation and morphology of 71 human trabecular bone samples. The ITS-based morphological analyses better characterize microarchitecture and help predict anis...

In this paper an alternaUve approach to the modelling of plates with a large number of holes is pres;nted. By means of plate theoPy, it is shown that perforated plates can be modelled by conventional orthouopic plates with modified elastic preponies. The modification of the elastic constants is derived by equalizing the strain-energy oftbe perforated and the ortholropic plate. The model oblaine...

By means of plate theory, it is shown that perforated plates can be modelled by conventional orthotropic plates with modified elastic properties. The modification of the elastic constants is derived by equalising the strain-energy of the perforated and the orthotropic plate. The model obt...

We present a theoretical study of wave propagation in two adjoining floating plates of different flexural rigidity, such as fast-ice sheets that abut across a pressure ridge, etc. Analytical formulas for the transmission and reflection coefficients for various conditions at the interface are obtained using the Wiener-Hopf technique for the case of semiinfinite elastic plates joined by a straigh...

An analysis of unsteady MHD flow of an electrically conducting visco-elastic fluid confined between two horizontal parallel non conducting plates in presence of a transverse magnetic field and Hall current is presented. The lower plate is a stretching sheet while the upper one is an oscillating porous plate, which is oscillating in its own plane. The motion of the fluid is produced by the stret...

The generalized plane quasistatic deformations of linear piezoelectric laminated plates are analyzed by the Eshelby–Stroh formalism. The laminate consists of homogeneous elastic or piezoelectric laminae of arbitrary thickness and width. The three-dimensional differential equations of equilibrium for a piezoelectric body are exactly satisŽ ed at every point in the body. The analytical solution i...

In this article, the axisymmetric stability of an elastic annular plate with distributed internal heat source under uniform constant compressive radial loading at outer edge is investigated. The governing and compatibility equations are taken from modified Karman’s equations, which solved by shooting method. effect density on critical load investigated discussed in detail. Numerical results wit...
