Seed layer formation by deposition of micro‐crystallites on a revolving substrate. Part II: application to some nonlinear effects

Acta Crystallographica Section B, EarlyView.
A method of averaging the material coefficients of crystallites deposited at an angle onto a revolving substrate isapplied to effective nonlinear dielectric, piezoelectric and elastic constants, as well as linear pyroelectric coefficients, for triclinic crystals.The matrix method of averaging material coefficients of crystallites deposited at an angle ...

The role of absorption in 3D electron diffraction dynamical structure refinement

Acta Crystallographica Section A, EarlyView.
This work establishes the role of absorption in 3D electron diffraction dynamical refinement, where its inclusion is shown to significantly affect refinement outcomes only in high‐Z materials at thicknesses approaching ξg.The role of absorption in 3D electron diffraction is established through analytical theory, simulation and dynamical refinement.

Modeling Nonlinear Acoustic Wave Propagation With Third‐Order Elastic Constants Using the Finite Element Method

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

Violoncello String Vibrations as an Example of Continuum Dynamics—Limits of Minimal Model Considerations

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Vibrations in string instruments and especially the excitation of their strings by bowing or plucking have been the subject of considerations and research for decades in textbooks and research papers. The current presentation collects some instructive measurement results with a violoncello and their interpretation in the framework of minimal ...

Enabling Hybrid Modeling in Commercial MBS Software: A Force‐Level Approach

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Hybrid modeling aims to combine physical and data‐driven models to increase simulation accuracy without losing physical interpretability. In the context of dynamic mechanical systems, this enables the compensation of modeling inaccuracies that arise from simplifications, missing effects, or uncertain parameters. In this work, a hybrid model is
