The von Neumann Stability Analysis of the Fixed‐Stress Schemes in Poroelastodynamics

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 4, Page 1939-1951, March 2026.
ABSTRACT We investigate splitting schemes based on the fixed‐stress sequential approach for poroelastodynamic problems. To assess numerical stability, we perform the von Neumann stability analysis on several fixed‐stress schemes for poroelastodynamics, including staggered, stabilized, and iterative methods. Our analysis reveals that while the staggered

Forced Response Analysis of Dynamic Systems With Inertia Nonlinearity by Applying the Multiharmonic Balance Method

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Nonlinear mechanical vibrations under harmonic forcing can be well approximated by Fourier series. For a finite number of harmonics, the error is minimized over one period of vibration. This technique, known as multiharmonic balance method (MHBM), is today widely used in academics as well as industrial applications, e.g., for friction‐damped ...

Three‐Dimensional Simulation of Crack Initiation in ice Shelves at Pinning Points

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Ice shelves are large ice masses floating on the ocean that are still connected to the inland ice of a glacier. Due to high elevations in the bathymetry, the ice shelf can be partially grounded. These areas are called ice rises that act as pinning points.

The Wavelet Galerkin Operator

open access: yes, 2003
In connection to wavelet theory, we describe the peripheral spectrum of the transfer operator. The solution involves the analysis of certain representations of the algebra generated by two unitaries $U$ and $T$ that satisfy the commutation relation $UTU^{-1}=T^N$.

Approximate Stability Analysis of Omega‐Stringer Stiffened Composite Panels

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Thin‐walled composite structures are widely used in weight‐critical applications such as aircraft and spacecraft. However, ensuring the stability of such structures under various load cases remains a key challenge in their design and optimization.

A comparison between characteristic lines and streamline upwind Petrov-Galerkin method for advection dominated problems

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2013
This article develops numerically the advection-diffusion equation problem, using Galerkin on characteristic lines and Streamline Upwind Petrov-Galerkin (SUPG) methods. The dominated advective conditions in the solved problem showed that for cases where

Fully Discrete Local Discontinuous Galerkin Approximation for Time-Space Fractional Subdiffusion/Superdiffusion Equations

open access: yesAdvances in Mathematical Physics, 2017
We focus on developing the finite difference (i.e., backward Euler difference or second-order central difference)/local discontinuous Galerkin finite element mixed method to construct and analyze a kind of efficient, accurate, flexible, numerical schemes
