Arbitrary Lagrangian–Eulerian Formulation in a Rotating Frame to Model Friction Spinning

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Friction spinning is a metal forming process that can be used to manufacture various shapes by rotating a metallic workpiece relative to a blunt tool. When used as a hot metal forming process, the relative velocity between workpiece and tool is increased until substantial heat is generated due to friction.

A Two‐Way Coupled Simulation Framework for the Prediction of Fire‐Induced Damage and Smoke Propagation in a Building

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The contribution is concerned with a fully coupled simulation methodology for fire‐induced damage in concrete structures. Fire events in buildings not only generate high temperatures and the spreading of smoke gases but also induce significant structural damages of the concrete structure.

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

open access: yesProceedings 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

Influence of Thermal Boundary Conditions on Heat Transfer in Turbulent Annular Pipes

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Turbulent concentric annular pipe flow with heat transfer is investigated using the stochastic one‐dimensional turbulence (ODT) model. In the present study, annular pipe flow is investigated at fixed bulk Reynolds number ReDh=17700$\mathit {Re}_{D_{\rm h}}=17\,700$ and Prandtl number Pr=0.71$\mathit {Pr}=0.71$ using two different thermal ...
