RISEFFECTS OF UNCERTAIN MECHANICAL PROPERTIES ON TIME HISTORY OF STRESSES (WAVE PROPAGATION) IN THICK HOLLOW CYLINDER MADE OF FUNCTIONALLY GRADED MATERIALS (FGM) USING A PROBABILISTIC ANALYSIS
In the present article, the dynamic analysis and radial wave propagation phenomenon of stress field in a functionally graded thick hollow cylinder subjected to sudden unloading (as a mechanical shock loading) are stochastically studied using...
Sensitivity analysis of ray tracing to the geometrical description of the environment
In ray-tracing-based propagation modelling, the electromagnetic field at the receiver is obtained by coherent summation of the fields of multipath components. It is therefore crucial to accurately calculate the phase of ...
Two Dimensional Stress and Displacement Wave Propagation Under Shock Loading in Saturated Porous Materials with Two Dimensional Functionally Graded Materails Using MLPG Method
The meshless local Petrov-Galerkin (MLPG) method is employed for dynamic analysis
of fully saturated porous materials under shock loading considering two directional functionally grading
patterns in constitutive ...
DEMETER observations of high latitude chorus waves penetrating the plasmasphere during a geomagnetic storm
Volcanic tremor masks its seismogenic source: Results from a study of noneruptive tremor recorded at Mount St. Helens, Washington
Influence of atmospheric structure and topography on infrasonic wave propagation
General templates for n-noded bar elements based on reduced representations and numerical dispersion reduction by optimized finite elements
Various kinds of finite elements are proposed and employed for one-dimensional wavefield
simulations, each of which has their own capabilities and disadvantages. This paper
deals with structural similarities ...
Dynamic response of multiwall boron nitride nanotubes subjected to impact
Dynamic behaviours of multiwall boron nitride nanotubes (MWBNNTs) with finite length were studied
by employing continuum structure. Multiple elastic shells with nonlinear model of van der Waals interactions were ...
An investigation of stress wave propagation in a shear deformable nanobeam based on modified couple stress theory
This paper presents a new investigation for propagation of stress wave in a nanobeam based on modified couple stress theory. Using Euler– Bernoulli beam theory, Timoshenko beam theory, and Reddy beam theory, the effect of ...
WAVE PROPAGATION AND MECHANICAL SHOCK ANALYSIS IN FUNCTIONALLY GRADED THICK HOLLOWCYLINDER USING A HYBRID MESH-FREE METHOD
In this paper, a mesh-free hybrid method based on generalized finite difference
(GFD) and Newmark finite difference (NFD) methods is presented to calculate the velocity of
elastic wave propagation and to study on dynamic behavior of FG...
