The Influence of Gradiations of Porous Structures Onto Their Effective Mechanical Behavior
ABSTRACT Hybrid porous materials exploit graded pore architectures to tailor their mechanical performance. Here, FFT‐based homogenization of three‐dimensional volume elements is used to study the influence of different gradation concepts in an aluminum matrix at a fixed solid volume fraction of 80%.

Rapid convergence of a Galerkin projection of the KdV equation
In this Note, it is shown that a Fourier Galerkin approximation of the Korteweg–de Vries equation with periodic boundary conditions converges exponentially fast if the initial data can be continued analytically to a strip about the real axis.

In this paper, we discuss the superconvergence of the local discontinuous Galerkin methods for nonlinear convection-diffusion equations. We prove that the numerical solution is ( k + 3 / 2 ) $(k+3/2)$ th-order superconvergent to a particular projection ...

ABSTRACT This paper addresses polytope element formulations, which facilitate flexible meshing of complex geometries. While two‐dimensional polygon elements have gained popularity, we focus specifically on less explored three‐dimensional polyhedral element formulations.

A Galerkin Method for a Gaseous Ignition Model
We consider a Galerkin procedure to solve a parabolic integrodifferential equation that arises in a gas combustion model. This model has been proposed by Kassoy and Poland, and subsequently analyzed by Bebernes, Eberly and Bressan.

Shooting Methods for Boundary Value Problems of Fractional Differential Equations
ABSTRACT We consider two‐point boundary value problems of fractional differential equations (FDEs) including a Caputo derivative with a fractional order in the range (0,1) or (1,2). The numerical solution of a boundary value problem is investigated using shooting methods.
