On the numerical homogenization of real polycrystalline microstructures
PAMM, Volume 22, Issue 1, March 2023., 2023 Abstract The FE2 method, cf. [1], a direct micro‐macro homogenization approach, has become a standard procedure for scale‐transition applications. Therein, the modeling of a micro‐heterogeneous material described by a representative volume element (RVE) based on realistic microstructures can give rise to a barely unmanageable computational effort ...

Berechnung von punktgestützten Verglasungen mit Senkkopfhaltern
ce/papers, Volume 5, Issue 1, Page 171-182, February 2022., 2022 Abstract Nach jetzigem Stand ist die Berechnung punktgestützter Verglasungen nach dem vereinfachten Verfahren der DIN 18008‐3 auf zylindrische Bohrungen mit Tellerhaltern beschränkt. Flächenbündige Senkkopfhalter mit konischer Bohrung im Glas werden nicht berücksichtigt.

Remarks on a primal‐dual interior point algorithm for single crystal plasticity
PAMM, Volume 21, Issue 1, December 2021., 2021 Abstract In the field of single crystal plasticity, different algorithms exist for the solution of the constitutive equations. They can be grouped into rate independent and rate dependent approaches, where both classes are governed by inherent shortcomings, as discussed in, e.g., [3].

GAMM-Mitteilungen, Volume 44, Issue 4, November 2021., 2021 Abstract This work presents multilayer phase‐field simulation of selective sintering process and the calculation of effective mechanical properties and residual stress of the microstructure using the finite element method. The dependence of the effective properties and residual stress on the process parameters, such as beam power and scan speed, are ...

GAMM-Mitteilungen, Volume 43, Issue 2, June 2020., 2020 Abstract Important conditions in structural analysis are the fulfillment of the balance of linear momentum (vanishing resultant forces) and the balance of angular momentum (vanishing resultant moment), which is not a priori satisfied for arbitrary element formulations.
