In this paper, a three dimensional analysis of arbitrary straight-sided quadrilateral nanocomposite plates are investigated. The governing equations are based on three-dimensional elasticity theory which can be used for both thin and thick nanocomposite plates. Although the equations can support all the arbitrary straight-sided quadrilateral plates but as a special case, the numerical results f...

In this study, the free vibration analysis of smart vibration control (SVC) systems based on Reddy – Levinson model and modified strain gradient theory is developed. This system consist of a micro beam at middle and two magneto-electro-elastic (MEE) composite micro beams at top and bottom which connected by enclosing elastic medium and simulated by Winkler and Pasternak foundation. The effects ...

In this paper, the unsteady flow of two immiscible fluids with heat transfer is studied numerically with a modified cubic B-spine Differential Quadrature Method. Generalized Couette two immiscible dusty (fluid-particle suspension) and pure (Newtonian) are considered through rigid horizontal channels for three separate scenarios: first non-porous plates heat transfer, second porous uniform s...

Given its versatility in drawing power from many sources the natural world, piezoelectric energy harvesting (PEH) has become increasingly popular. However, capacities could be enhanced further. Here, a mathematical model that accurately simulates dynamic behavior and harvested can facilitate further improvements performance of devices. One goals this study is to create dependable reduced-order ...

in this study, nonlocal nonlinear instability and the vibration of a double carbon nanotube (cnt) system have been investigated. the visco-pasternak model is used to simulate the elastic medium between nanotubes, on which the effect of the spring, shear and damping of the elastic medium is considered. both of the cnts convey a viscose fluid and a uniform longitudinal magnetic field is applied t...

Abstract Changes in climate intensity and frequency, including extreme events, heavy intense rainfall, have the greatest impact on water resource management flood risk management. Significant changes air temperature, precipitation, humidity are expected future due to change. The influence of change hazards is subject considerable uncertainty that comes from model discrepancies, bias correction ...

In the present study, three layers of the ascending aorta in respect to the time and space at various blood pressures have been simulated. Two well-known commercial finite element (FE) software have used to be able to provide a range of reliable numerical results while independent on the software type. The radial displacement compared with the time as well as the peripheral stress and von Mises...

Um Synergieeffekte aus der Verschneidung verschiedener Datenbestände nutzen und auf diese Weise neue Informationen gewinnen zu können, werden heutzutage zunehmend integrierte Datenbestände beispielsweise in Form von Data Warehouses erzeugt. Häufig erfolgt die Erzeugung integrierter Datenbestände jedoch nicht durch die Urheber der verschiedenen Datenquellen selbst, sondern durch andere Personen,...
