Optimale Versuchsplanung und Modellbildung zur Parameteridentifikation für inhomogene Probleme
The reliable prediction of numerical simulations requires not only physically based mathematical modeling but also determination of the associated model constants based on experimental data. However, deficiencies of experimental data as well as model deficiency may have an impact on the stability of the identified parameters. This application is ...

Experimentelle und numerische Ermittlung der Korrelationen zwischen den Prozessgr??en der thermo-mechanischen Werkstoffbehandlung und den mechanischen Eigenschaften bei gradierten Mischgefügen mit bimodaler Korngr??enverteilung
The aim of the project is the simulation-based determination of the relationships between process variables of thermo-mechanical processing and the resulting graded microstructure with bimodal grain size distribution.To reduce CO2 emissions in the transport sector, the approach of load-adapted components is increasingly being pursued to reduce the ...

Ein Zweiskalenmodell für Sch?digungsvorg?nge bei der spanenden Bearbeitung von kohlenstofffaserverst?rkten Kunststoffen
This project includes an experimental characterization of the carbon-fiber-reinforced plastic (CFK) composite and its components, material modeling, CFK machining tests, and simulation-supported analyses of CFK machining. Its main objective is the simulation-supported prediction of machining damage mechanisms of CFK. Four basic relevant damage ...

Zielorientierte adaptive Finite Elemente zur Parameteridentifikation konventioneller und additiver mikromorpher Kontinuumsmodelle
Due to deficiencies of local continua, in particular pathological mesh dependency of FE solutions on the numerical side and failure to simulate length scale dependent problems on the theoretical side, generalized continuum theories have wide areas of applications. In this project, we address the class of micromorphic continua, containing micropolar ...

Zielorientierte Adaptivit?t für nichtlineare Homogenisierungen mittels hierarchischer Modelle
The development and the production of innovative products using novel materials require in-depth knowledge of simulation methods for a safe design of components and machines. The increasing use of heterogeneous materials like composites in the industrial praxis has made the finite element (FE) simulation using homogenization techniques a ...

Fuzzy-stochastische Methoden für die polymorphe Unsch?rfemodellierung von Leichtbaustrukturen
The overall aim of the research project is to transfer the polymorphic uncertainty models developed in the first funding period into the life cycle of hybrid lightweight structures. In particular, the manufacturing as well as the subsequent use during service time of fiber reinforced plastics (FRPs) in hybrid systems are investigated. During the ...

Experimente, Modellierung und Parameteridentifikation bei inhomogenen Verzerrungszust?nden von Kunststoffen mit induzierter Anisotropie
The project deals with the experimental characterization, modeling and parameter identification of polycarbonate (PC) films which receive a so-called "self-reinforcement" by cold-forming (pre-stretching). In this way, the initially isotropic material experiences a strain-induced anisotropy. Thus, properties such as strength and ductility can be ...
