This work introduces an optimisation-based scheme for the calibration of viscoelastic material models that are coupled to gradient-enhanced damage in a finite strain setting. The parameter identification scheme is applied to a self-diagnostic poly(dimethylsiloxane) (PDMS) elastomer, where so-called mechanophore units are incorporated within the polymeric microstructure. The present contribution, however, focuses on the purely mechanical response of the material, combining experiments with homogeneous and inhomogeneous states of deformation. In effect, the results provided lay the groundwork for a future extension of the proposed parameter identification framework, where additional field-data provided by the self-diagnostic capabilities can be incorporated into the optimisation scheme.</jats:p>","lang":"eng"}],"publication":"Materials","issue":"14","volume":13,"user_id":"85414","publisher":"MDPI AG","_id":"62777","status":"public","quality_controlled":"1","citation":{"apa":"Schulte, R., Ostwald, R., &#38; Menzel, A.

Attackers might exploit vulnerabilities in the physical configurations, control systems, or accessibility through internet connections. For CPS, two challenges are combined: Firstly, discipline-specific security measures should be applied. Secondly, new measures have to be created to cover interdisciplinary impacts. For instance, faulty software configurations in cyber-physical production systems (CPPS) might allow attackers to manipulate the correct control of production processes impacting the quality of end products. From liability and publicity perspective, a worst-case scenario is that such a corrupted product is delivered to a customer. In this context, security-oriented fault-tolerance in Systems Engineering (SE) requires measures to evaluate interdisciplinary system designs with regard to potential scenarios of attacks. The paper at hand contributes a conceptual threat modelling approach to cover potential attack scenarios.

Their main task is to prevent oil from exiting the system and dirt particles from entering the system. When this function is not fulfilled, a leakage can occur and cause excessive damage after certain operating times, such as gear failure due to insufficient lubrication. This is the reason for the high level of current research interest in seals. The sealing function of RSSR occurs in the contact area between the sealing lip and the shaft. The contact takes place over a very small contact width of approximately 1 &mu;m. These extremely small dimensions and the complex relationships between the functional influencing variables on the radial shaft sealing system make it difficult to simulate wear on the sealing ring. The energetic consideration of the wear process offers the possibility of quantifying influencing variables more easily by their energetic contribution, which can be determined experimentally. Based on experimentally measured total friction moments, and with the help of a semi-analytical (SA) solid contact model based on the half-space theory, this paper presents a modelling approach for the calculation of wear at the sealing ring. The model presented in this work differs from the existing models in two ways. The first particularity is the coupling of SA method with finite element method (FEM) for the resolution of the contact between the sealing lip and the shaft, allowing a fine discretization of the contact zone (by SA method) and the consideration of the structural behavior (by FE method). The SA method compared to the commonly used FEM presents a great saving in computation time. The second particularity is the use of the real data obtained during the wear tests. Most existing simulation models are based purely on contact pressure. This means that through the contact pressure obtained by simulation and a given sliding distance value, a friction energy will be estimated which will be used in a next step using a wear model such as Archad&rsquo;s to calculate the wear rate. In this publication the value of friction energy was obtained directly on an experimental basis and a more appropriate wear law, such as Fleischer&rsquo;s, taking into account the friction conditions, was used to estimate the wear rate."}],"issue":"2","publication":"Lubricants","doi":"10.3390/lubricants8020015","language":[{"iso":"eng"}],"date_updated":"2026-07-18T13:20:23Z","intvolume":"         8","year":"2020","title":"Friction Energy-Based Wear Simulation for Radial Shaft Sealing Ring","publication_identifier":{"issn":["2075-4442"]},"author":[{"first_name":"Flavien","last_name":"Foko Foko","full_name":"Foko Foko, Flavien"},{"full_name":"Heimes, Julia","first_name":"Julia","last_name":"Heimes"},{"last_name":"Magyar","first_name":"Balázs","full_name":"Magyar, Balázs","id":"97759"},{"full_name":"Sauer, Bernd","first_name":"Bernd","last_name":"Sauer"}]},{"type":"journal_article","department":[{"_id":"146"}],"date_created":"2022-12-15T09:41:22Z","abstract":[{"text":"Regarding the increasing demand in seal lifetime and energy efficiency, a detailed microscopic simulation is necessary—as an addition to experimental investigations—to better understand and improve radial shaft seals.

However, inhomogeneous and hardly controllable thermal effects during manufacturing limit the build reproducibility. The present work focuses on temperatures within so-called part cakes, their time dependency and their influence on process quality. Therefore, a temperature measurement system is implemented into a commercial laser sintering machine. Based on the experimental data a model to simulate heat transfer within part cakes is set up. Individual thermal histories during processing are successfully correlated with position dependent powder ageing effects. Another focus is on the analysis of a recycling optimized material.

Die Bauteile müssen jedoch auch speziell auf die Verfahren angepasst sein, um sicher, fehlerfrei und kostengünstig produziert werden zu können. Mit konventionellen Konstruktionsverfahren sind solche Strukturen nur schwer erzeugbar.\r\nIm Rahmen dieser Arbeit wird daher eine Methodik zur intelligenten Optimierung von Produktgeometrien, angepasst an die additive Fertigung, entwickelt. Dies beinhaltet die automatische Erzeugung von anwendungsfallspezifisch optimierten Geometrien sowie deren Überführung in Datenstrukturen, welche in konventionellen CAD-Systemen nutzbar sind. Als grundlegendes Werkzeug wird dabei die Topologieoptimierung verwendet, welche hochaufgelöst durchgeführt und im Anschluss mit hoher Qualität geglättet und weiterverarbeitet werden muss. Hierzu wurde ein durchgängiger voxelbasierter Ansatz gefunden, der auch die Anpassung der Geometrien an die additive Fertigung erlaubt. Die Entwicklung und Funktionalität des Ansatzes wird auf Basis mehrerer Beispielbauteile gezeigt. Das Ergebnis der Optimierungen sind hochkomplexe, im Detail optimierte und an die additive Fertigung angepasste Strukturen.

Problematisch ist dabei jedoch die geringe Erfahrung der Unternehmen mit der additiven Fertigung und ihren Besonderheiten. Ein Vergleich mit anderen Fertigungsverfahren muss dabei über eine reine Kostenkalkulation hinausgehen, um zusätzliche Potentiale und Einschränkungen abwägen zu können. Die vorliegende Arbeit gibt daher einen Überblick über die wesentlichen Einflussfaktoren Kosten, Zeit und Qualität und es wird auf dieser Basis eine Entscheidungsunterstützung entwickelt, die bei der Identifizierung vorteilhafter Einsatzmöglichkeiten für die additive Fertigung hilft. Da die additive Technologie auch signifikante Änderungen im Bereich der Supply Chain erzielen kann, liegt der Fokus des Einsatzgebietes auf der zeitkritischen Ersatzteilversorgung, betrachtet am Beispiel der Luftfahrtindustrie. In diesem Kontext ist es Ziel und Zweck der Arbeit, die oftmals isoliert betrachteten drei Bereiche Kosten, Zeit und Qualität zu einem ganzheitlichen Vergleich zu kombinieren. Die entwickelte Entscheidungsunterstützung ist dabei auf Basis einer funktionserweiterten Tabellenkalkulation als Demonstrator umgesetzt worden.","lang":"ger"}],"date_created":"2021-09-21T11:39:07Z","type":"dissertation","department":[{"_id":"144"},{"_id":"219"},{"_id":"624"}],"year":"2019","title":"Entwicklung einer Entscheidungsunterstützung für den Einsatz Additiver Fertigung in der zeitkritischen Ersatzteilversorgung","author":[{"first_name":"Gereon","last_name":"Deppe","full_name":"Deppe, Gereon"}],"publication_identifier":{"isbn":["978-3-8440-6402-5"]},"date_updated":"2022-01-06T06:56:34Z","intvolume":"         9","main_file_link":[{"url":"https://www.shaker.de/de/content/catalogue/index.asp?lang=de&ID=8&ISBN=978-3-8440-6402-5&search=yes"}],"language":[{"iso":"ger"}],"series_title":"Forschungsbericht des Direct Manufacturing Research Centers","supervisor":[{"last_name":"Koch","first_name":"Rainer","full_name":"Koch, Rainer"}],"citation":{"mla":"Deppe, Gereon. <i>Entwicklung einer Entscheidungsunterstützung für den Einsatz Additiver Fertigung in der zeitkritischen Ersatzteilversorgung</i>.
