Image‐Based Flaw Identification Using Convolutional Neural Network
International Journal of Mechanical System Dynamics, Volume 5, Issue 4, Page 694-706, December 2025.ABSTRACT Flaw detection in structures is crucial for ensuring structural integrity and safety across various engineering applications. Traditional nondestructive evaluation (NDE) techniques often face challenges in accurately identifying and characterizing flaws, particularly when dealing with complex geometries and strain fields.

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.

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 ...

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.

Evaluation of Numerical Methods for Dispersion Curve Estimation in Viscoelastic Plates
EngThis study aims to evaluate the effectiveness of five analytical and semi-analytical methods for estimating Lamb wave dispersion in viscoelastic plates—the Rayleigh–Lamb solution, the Global Matrix Method (GMM), the Semi-Analytical Finite Element (SAFE ...
