Analysis of Guided Wave Propagation in a Multi-Layered Structure in View of Structural Health Monitoring

Applied Sciences, 2019
Guided waves (GW) are of great interest for non-destructive testing (NDT) and structural health monitoring (SHM) of engineering structures such as for oil and gas pipelines, rails, aircraft components, adhesive bonds and possibly much more.

VERTICAL VIBRATIONS OF BASE ISOLATED MACHINEFOUNDATIONS

Journal of Engineering, 2010
Vibration of base isolated machine foundations has been studied using the Scaled Boundary Finite Element Method (SBFEM) and the cone model method. The dynamic stiffness of soil supporting rigid massless foundation was determined.

A Comparative Study of Polygonal Element Formulations for Linear Elasticity

Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 4, December 2025.
ABSTRACT With the rising complexity of architectural design, a growing interest in topology optimization, and the increasing need to model crack propagation, there is a higher demand for highly flexible geometry descriptions that go hand in hand with robust element formulations.

Towards the Efficient Simulation of Large‐Scale Soil‐Structure Interaction Problems Using the Scaled Boundary Finite Element Method

Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 4, December 2025.
ABSTRACT Modeling wave propagation in soil using conventional finite element methods necessitates the simulation of extensive spatial domains to prevent reflections at artificial boundaries. Classical absorbing boundary conditions can be used to mitigate this problem, but must be placed at a considerable distance from the area of interest to ensure ...

Element‐Based Internal Variable Formulations for Finite Element Discretizations in FFT‐Based Homogenization Methods

International Journal for Numerical Methods in Engineering, Volume 126, Issue 21, 15 November 2025.
ABSTRACT Although finite elements were made available for FFT‐based computational homogenization methods, they are seldomly used for inelastic computations because traditionally the constitutive law is evaluated at each quadrature point of the element, making the storage of that many internal variables necessary, as well.

A scaled boundary shell formulation in isogeometric analysis for static and dynamic analysis

Proceedings in Applied Mathematics and Mechanics, Volume 24, Issue 3, October 2024.
Abstract In modern applications of computer‐aided design (CAD) for the analysis of shell structures, isogeometric analysis is a powerful tool that integrates both design and analysis. An exact geometry description and a straightforward computation without loss of information are advantageous, especially for shell structures such as roofs, satellite ...

Stabilization‐free virtual element method for 2D elastoplastic problems

International Journal for Numerical Methods in Engineering, Volume 125, Issue 15, 15 August 2024.
Abstract In this paper, a novel first‐ and second‐order stabilization‐free virtual element method is proposed for two‐dimensional elastoplastic problems. In contrast to traditional virtual element methods, the improved method does not require any stabilization, making the solution of nonlinear problems more reliable.

SBFEM with perturbation method for solving the Reynolds equation

Proceedings in Applied Mathematics and Mechanics, Volume 24, Issue 2, August 2024.
Abstract Rotordynamic simulations with nonlinear hydrodynamic bearing forces require a solution of the Reynolds equation at every time step. As a computationally efficient alternative to the standard numerical methods, a semi‐analytical solution based on the scaled boundary finite element method (SBFEM) was developed recently.
