Thermal extrusion of a non-linear viscoelastic solid inside a long cylindrical tube

Poiseuille and Thermal-Creep Flowin a Cylindrical Tube

A version of the discrete-ordinates method is used to solve, for the case of flow in a cylindrical tube, the classical Poiseuille and thermal-creep problems based on the Bhatnagar, Gross, and Krook model in the theory of rarefied-gas dynamics. In addition to the development of a discrete-ordinates solution that is valid for a wide range of the Knudsen number, the solution is evaluated numerical...

Viscoelastic impact between a cylindrical striker and a long cylindrical bar

Embedded Recovery Methods for Viscoelastic Flow past a Sphere in a Cylindrical Tube

The motivation for this study is to capture the superior accuracy properties of recovery methods and their application to the numerical solution of nonlinear viscoelastic ows. For velocity gradient recovery, local direct methods are compared to Galerkin least squares methods. Superconvergence properties are intrinsic. We compare and contrast averaging and patch recovery approaches. We investiga...

Non-linear Response and Dynamic Buckling Analysis of a Cylindrical Sandwich Panel with a Flexible Core under Blast Loading

In this paper, three-dimensional displacement response of a cylindrical sandwich panel with compressible core under the action of dynamic pulse loading is addressed using the extended high order sandwich panel theory. Also, local dynamic pulse buckling of facesheets is studied by considering the Budiansky-Roth buckling criterion. It is assumed that the sandwich panels consist of orthotropic fac...

Non-Linear Analysis of Asymmetrical Eccentrically Stiffened FGM Cylindrical Shells with Non-Linear Elastic Foundation

In this paper, semi-analytical method for asymmetrical eccentrically stiffened FGM cylindrical shells under external pressure and surrounded by a linear and non-linear elastic foundation is presented. The proposed linear model is based on two parameter elastic foundation Winkler and Pasternak. According to the von Karman nonlinear equations and the classical plate theory of shells, strain-displ...
