In this article, we demonstrate the flexibility of a multi-domain approach combined with the
extended finite element method by addressing the modeling and simulation of keyhole-based …

Cold forming generally allows the fast generation of parts with very low tolerances. In addition,
mechanical properties are improved, if work hardening materials are used. Transferring …

Modeling and computation of a process with solid‐liquid‐solid phase transitions and a free
capillary surface is discussed. The main components of the model are heat conduction, a free …

In modern engineering, various complex processes can be modeled by systems of partial
differential equations (PDEs) which may be nonlinear and coupled. Problems involving …

To overcome the disadvantages like buckling in upsetting processes in micro range, an
alternative two-stage shaping process has been developed. This two-stage process consists of a …

In this paper, simulation approaches for the partial melting of metallic workpieces in micro
scale are presented. The underlying model considers heat transport in the whole workpiece, …

In micro manufacturing, a precise configuration of manufacturing processes constitutes an
essential factor for success. The continuing miniaturization of work pieces results in ever …

We present two models for engineering processes, where thermal effects and time-dependent
domains play an important role. Typically, the parabolic heat equation is coupled with …

In this article, a 3D finite element simulation of a material accumulation process based on
rod end and blank end melting is discussed. This process represents the first step of a two-…

A modeling and simulation approach for problems with solid‐liquid‐solid phase transitions
and a free surface, feasible for material accumulation processes based on laser‐based free …
