In this paper the buckling coefficient of FGM rectangular plates calculated by the new version of differential quadrature method (DQM). At the first the governing differential equation for plate has been calculated and then according to the new version of differential quadrature method (DQM) the existence derivatives in equation , convert to the amounts of function in the grid points inside of ...

Since the last decades and due to the high capacity of storage, data is being increasingly available in information society, which has led to the need for valid tools for its modelling and analysis such as Knowledge Discovery in Databases (KDD) methods (known as data mining methods). However, many problems go along with the business application of data mining. In fact, the quality of the genera...

This manuscript develops for the first time a mathematical formulation of dynamical behavior bi-directional functionally graded porous plates (BDFGPP) resting on Winkler–Pasternak foundation using unified higher-order plate theories (UHOPT). The kinematic displacement fields are exploited to fulfill null shear strain/stress at bottom and top surfaces without needing factor correction. gradation...

As a first endeavour, nonlinear dynamic response of the glass fibre-reinforced​ epoxy (GRE) laminated composite cylindrical shells under an impulse load is investigated based on first-order shear deformation theory (FSDT) shells. Green’s strain and von Kármán hypothesis are assumed to consider geometrical nonlinearity due large in model. A new solution procedure composed differential quadrature...

Under the influence of axial forces and uniform temperature variations, thermal buckling postbuckling composite beams reinforced functionally graded multilayer graphene platelets (GPLs) resting on nonlinear elastic foundations are examined. The Halpin-Tsai model is used to calculate modulus each layer GPL-reinforced (GPLRC). According virtual work principle, governing equations for beam obtaine...

The dynamics of the interaction between immiscible fluids is relevant to numerous complex flows in nature and industry, including lubrication coating processes, oil extraction, physicochemical separation techniques, etc. One most essential components flow fluid interface, which must be consistently monitored. In this article, unsteady two i.e., an Eringen micropolar Newtonian liquid considered ...

The hydrodynamics of immiscible micropolar fluids are important in a variety engineering problems, including biofluid dynamics arterial blood flows, pharmacodynamics, Principle Boundary layers, lubrication technology, short waves for heat-conducting fluids, sediment transportation, magnetohydrodynamics, multicomponent hydrodynamics, and electrohydrodynamic. Motivated by the development biologic...
