Large displacement transient analysis of FGM super-elliptic shells using GDQ method

Thin-Walled Structures, 2019
Abstract Current work concentrates on large displacement dynamic analysis of super-elliptic (SE) shells made of functionally graded materials (FGMs) employing generalized differential quadrature (GDQ) technique. SE shells can be in quasi-rectangular, elliptical or cylindrical shell forms according to the parameters in super-ellipse formulation.

GDQ criteria of viability for differential inclusions

2007 European Control Conference (ECC), 2007
The viability problem for differential inclusions is studied. It is assumed that the right-hand side of the differential inclusion is given by a multifunction (an orientor field) defined by the graph of another multifunction (called a constraint multifunction), which depends on time.

Analysis of hydrodynamic journal bearing with GDQ method

Digest of the Asia-Pacific Magnetic Recording Conference, 2003
Generalised Differential Quadrature (GDQ) method is a high-order numerical method. It uses the information on all grid points to approach the derivatives of the unknown function. With GDQ method, it is possible for us to obtain the same accurate results but use less grid points and less computing time than that of FDM/FEM.

Numerical analyses of piezoelectric materials with the GDQ method

Computational Materials Science, 2006
The piezoelectric strip under mechanical and electric loads is studied by using the two-dimensional generalized differential quadrature (GDQ) method. The discretized equations of boundary condition for stress and electric potential function are directly applied into the discretized governing equations to make the computation of stress and electric ...

Numerical Simulation of Taylor Vortex Flow by GDQ Method

Fluids Engineering, 2000
Abstract In this study, the GDQ method was used to simulate a specific flow regime, Taylor vortex flow, of the motion of fluids between two concentric cylinders with rotating inner cylinder and stationary outer cylinder. An approach combining the SIMPLE strategy and GDQ discretization based on non-staggered mesh was proposed to solve the

Free vibration analysis of shells of revolution using GDQ method

2006
In this paper, the Generalized Differential Quadrature (GDQ) Method is applied to analyze the dynamical behaviour of double curved shells of revolution. The GDQ method was developed to improve the differential quadrature (DQ) method for the computation of weighting coefficients [1]. It has been found that the GDQ technique can obtain accurate numerical
