چکیده

In this article we consider the linear elasticity problem in an axisymmetric three dimensional domain, with data which are and have zero angular component. The weak formulation of reduces to a two on meridian involving weighted integrals. is formulated mixed method framework both stress displacement treated as unknowns. symmetry condition for tensor weakly imposed. Well posedness continuous its discretization shown. Two approximation spaces discussed corresponding numerical computations presented.

Approximation of Axisymmetric Darcy Flow

In this article we investigate the numerical approximation of the Darcy equations in an axisymmetric domain, subject to axisymmetric data. Rewriting the problem in cylindrical coordinates reduces the 3-D problem to a problem in 2-D. This reduction to 2-D requires the numerical analysis to be studied in suitably weighted Hilbert spaces. In this setting the Raviart-Thomas (RT) and Brezzi-Douglas-...

Axisymmetric Modes of Rotating Relativistic Stars in the Cowling Approximation

Axisymmetric pulsations of rotating neutron stars can be excited in several scenarios, such as core-collapse, crust and core-quakes and binary mergers and could become detectable either in gravitational waves or high-energy radiation. Here, we present a comprehensive study of all low-order axisymmetric modes of uniformly and rapidly rotating relativistic stars. Initial stationary configurations...

Multirate integration of axisymmetric step-flow equations

We present a multirate method that is particularly suited for integrating the systems of Ordinary Differential Equations (ODEs) that arise in step models of surface evolution. The surface of a crystal lattice, that is slightly miscut from a plane of symmetry, consists of a series of terraces separated by steps. Under the assumption of axisymmetry, the step radii satisfy a system of ODEs that re...
