Digital lecture series for forming technology starts on December 3, 2020
Registration is now open
On December 3, 2020, the first digital edition of the “Lecture Series Forming Technology” will take place in the 2020/21 winter semester. The industrial lectures offer application-related reports from industrial practice. They are organized by the IUL in order to promote the direct exchange between academia and industry in teaching and to allow both sides to benefit from the advantages of direct encounter.
Keynote Speech and Article “Damage in Metal Forming”
Together with Pierre-Olivier Bouchard (MINES ParisTech, France), Stefania Bruschi (University of Padova, Italy) and Cem Tasan (Massachusetts Institute of Technology, USA), A. Erman Tekkaya published the keynote paper “Damage in Metal Forming” in the CIRP Annals. The content was significantly influenced by the findings obtained in TRR 188. The presentation is available here: https://www.youtube.com/watch?v=98WD1SLvLE0.
Article in "Mechanics Research Communications"
This paper presents and validates a new simple mechanical model that allows a predictive estimation of the forming history for innovative high-speed forming processes. In particular, this model allows the evaluation of different pulse loads and material models within seconds without the need for complex finite element simulations.

New Project on Press Hardening
|Process steps of press hardening: a) rapid conductive heating, b) forming and hardening by tool cooling|
On September 1, 2020, the joint project "Analysis of the application potential of roll-clad MnB-Cr steel composites for press hardening", jointly proposed by the IUL and the IBF of RWTH Aachen University and funded by the DFG, started. The project investigates the improvement potential of the press hardening process by the use of roll-clad steel composites. The use of corrosion-resistant stainless steel cover layers should allow high heating rates and short holding times, which are not possible with currently used materials. In addition to the time savings achieved by a faster heating strategy, the project will investigate the possibility of producing load-adapted lightweight components by varying the layer ratios of core and cover layers.

Current Open Source Publication Shows Possibilities of Lightweight Components in Forming Technology
|Components that can be produced by forming processes, taking into account lightweight components in automotive engineering|
A current open source publication in the Springer Journal "Automotive Innovation" entitled "Lightweight in Automotive Components by Forming Technology" provides an overview of the possibilities in forming technology regarding lightweight components using the example of automotive components. The article focuses on research projects already carried out as well as ongoing at the IUL and uses the example of the electric car and the conventional car with combustion engine to demonstrate the wide range of forming processes that are possible to produce lightweight components. The article is freely available online at Springer: https://link.springer.com/article/10.1007/s42154-020-00103-3.

New Project on Torsion Test
|Schematic structure of the in-plane torsion test|
On July 1, 2020, the project "Preparation of a test specification for the in-plane torsion test", funded by the BMWi and AiF/FOSTA, started. Within the project, a virtual kick-off meeting with project partners from automotive engineering, steel production and metrology took place on July 21, 2020. The research project aims to achieve a widespread industrial use of the in-plane torsion test by standardizing the test procedure and the preparation of a test specification. For this purpose, the IUL is investigating the influences of various process parameters as well as the influence of specimen production and geometry on the test results and, on the basis of these, is defining suitable test conditions for a standardized test sequence.

New Project on Forming of Hybrid Metal-Plastic Compounds by Joining
As part of the joint project AutoFit (Automated assembly and non-destructive testing of pipe-fitting joints) the IUL is investigating the forming of joint hybrid metal-plastic compounds for fuel lines in aircraft construction. In addition to the different material behavior of the join partners, this novel set of requirements including fluid density, electrical conductivity and resistance against high acceleration forces during flight operations can be considered a central challenge. In the project both working media and active energy-based joining processes are used for this purpose.This project has been running since July 1, 2020, and it is funded by the Federal Ministry for Economic Affairs and Energy.

IUL congratulates MMT student on scholarship from the Industrieverband Massivumformung e. V.
As part of the promotion of young talents by the Industrieverband Massivumformung e. V. (IMU) Mr. Tanmoy Rakshit was awarded a scholarship on 17 June 2020. Due to current restrictions, the ceremonial awarding of the scholarship will be postponed until next year’s annual conference. Prof. Tekkaya expresses his delight and gratitude to the Industrieverband and congratulates the scholarship holder he had nominated.
Mr. Rakshit writes his master’s thesis on the development of damage during rotary swaging of monobloc tubular shafts in cooperation with GKN Driveline, a member company of the IMU, at the Institute of Forming Technology and Lightweight Components. The IUL congratulates Mr. Rakshit on this fantastic success.

Digital Doctoral Examinations at the IUL
The IUL team congratulates the successful doctoral candidates
Studies, teaching and research continue at the IUL despite the measures currently required due to the coronavirus. One impressive demonstration of this is the fact that two doctoral examinations were digitally conducted within two weeks.
Rickmer Meya's presentation on "Damage-controlled Sheet Metal Bending Using Compressive Stress Superposition" was held on 14 May 2020. Oliver Hering delivered his presentation on 25 May on the subject of "Damage in Cold Forging: Development, Effects and Control". Both lectures were streamed on the IUL homepage in order to make them available to the general public.
The IUL extends its sincere congratulations to the new doctors!
Aktuelle Ankündigung zu Lehrveranstaltungen im Sommersemester 2020
in diesem Semester (SS2020) werden alle Lehrveranstaltungen des IUL in rein digitaler Form, d. h. in Moodle ohne Präsenzveranstaltungen, stattfinden. Die einzige Ausnahme hiervon bilden schriftliche Klausuren zum Ende des Semesters hin. Darüber und über alle aktuellen Informationen werden Sie in den jeweiligen Moodle-Kursen frühestmöglich informiert. In den jeweiligen Moodle-Räumen finden Sie zudem Details, was digitale Lehre in den einzelnen Fällen beinhaltet, die Einschreibeoptionen und wie Sie in Kontakt mit den Vorlesungsbetreuenden treten können. Nur dort finden Sie die aktuellsten Informationen zu Ihrem jeweiligen Kurs. Die Links zu den Kursen finden Sie unter http://iul.eu/de/lehre mit Klick auf den entsprechenden Kurs.
Auch die zeitnahe Korrektur von bereits durchgeführten Klausuren wird durch die aktuelle Lage erschwert. Die Noten von bereits vollständig korrigierten Prüfungen werden wir schnellstmöglich im BOSS-System eintragen. Nach erfolgter Klausureinsicht werden die Noten im BOSS-System im Bedarfsfall natürlich nachträglich korrigiert. Die Veröffentlichungen von noch nicht vollständig korrigierten Prüfungen ist bis auf unbestimmte Zeit verschoben.
all of the IUL’s courses in this semester (SS2020) will entirely take place in a digital manner. That means there will be no part with physical attendance required and moodle is the platform used for all the courses. The only exception here are written exams which will take place at the end of the semester. You will find all information, including new developments regarding a course in the respective moodle course. There you will find all the details regarding enrollment, the digital learning tools used and how to contact the lecture supervisor. Only in moodle you’ll find the latest information on a particular course. The links to the courses are provided at http://iul.eu/de/lehre by clicking on the desired course.
Also the correction of exams is currently suspended. Exams which are already corrected completely will be entered in the BOSS system as soon as possible. After the review of the exams the grades in the BOSS system will be corrected if necessary. The publication of exam grades that have not yet been completely corrected is postponed indefinitely.
