Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT Due to the widespread usage of specialized piezoelectric actuators in various applications, accurate simulations have become key components of modern design processes. Although simulation tools for piezoelectric devices are widely available, nonlinear effects, which occur when exciting near resonance at elevated amplitudes, are often neglected

Reconfigurable Computing in Neural Network‐Enhanced Finite Element Analysis in Structural Dynamics
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT In the present study, artificial neural networks (ANNs) trigger a better physically plausible initial guess in the Newton–Raphson scheme of an implicit material integration scheme of rate‐dependent viscoplastic dynamic response of plate structures in an in‐house finite element (FE) solver.

A Novel Non‐Torque Dynamic Load Decoupling Method for Large Wind Turbine Nacelle Test Bench
Wind Energy, Volume 29, Issue 10, October 2026.ABSTRACT Accurate reproduction of non‐torque dynamic loads is a key challenge for full‐scale wind turbine nacelle test benches, where the nacelle‐level drivetrain is validated under controlled multi‐degree‐of‐freedom mechanical loading. This study focuses on the shaft‐conjugate load application unit (LAU) adopted in the 25‐MW‐class full‐scale wind ...
