23rd GAMM Seminar on Microstructures, 2024

Ruhr University Bochum, January 25-26, 2024
Young Researcher's Meeting on January 25, 2024

 

The GAMM Seminar on Microstructures is the annual meeting of the  GAMM activity group on Analysis of Microstructures. This year's workshop is organized in cooperation with SPP 2256 "Variational Methods for Predicting Complex Phenomena in Engineering Structures and Materials" funded by the German Science Foundation. The workshop will focus on various aspects of microstructures in solid mechanics, material science, and applied mathematics:

  • Modeling materials with microstructure (plasticity, damage, phase transitions, electro-magneto-mechanics, ...)
  • Experimental results on the formation and evolution of microstructure (lamination, phase transformation, ...)
  • Mathematical analysis, variational formulations, non-convex problems, relaxation methods
  • Multiscale methods and computational tools for the determination of effective properties of microheterogeneous materials

The workshop gives the opportunity to discuss and to compare different approaches to the above fields. It provides a platform for the interaction among young and established researchers in solid mechanics, mathematics, and material science.

Young Researcher's Meeting
  
The Young Researchers' Meeting takes place on Thursday from morning till noon. The aim of the session is to give especially young researchers, who are at the beginning stages of their Ph.D., an opportunity to present their work so far and discuss current challenges. Besides these talks, two keynote speakers, who are in the earlier stages of their careers (PostDoc, Junior Professor), will present their research and give thought-provoking impulses. If you wish to attend the Young Researchers' Meeting and would like to give a talk, please select the corresponding options in the registration form. We are looking forward to seeing you in Bochum!

Getting there

 

Maps and general information

Please check the webpage How to get to RUB for maps of the university campus and various option to get to Ruhr-University Bochum. For your convenience, we have to extracted the essential information below:

By plane

The closest major international airport is Dusseldorf International Airport (DUS) which is well connected to Bochum via the Deutsche Bahn. A train from the airport to Bochum typically takes around 50 minutes.

The Dortmund Airport is closer to Bochum, however getting to down town Bochum by public transport also takes around 50 minutes.

By train

Bochum main station (Bochum Hbf) is right down town and well connected to the university via the U35 subway line (ca. 15 min. ride). See "By Subway".
Unfortunately, long-distance trains do not reach Bochum main station due to construction work. Please check our travel information (see above) for recommended connections.

By subway

From the central train station hop on the U35 in the direction of "Ruhr-Universität" or "Hustadt" and disembark at "Ruhr-Universität". The convention center is a short walk away (ca. 700m).

Alight from the subway, go up the stairs, turn right and then continue walking straight passing the library and the audimax (large circular building).

By car

Please check the webpage How to reach us by car for detailed information and maps for arrival by car and parking at RUB.

Accessibility

Although our university is accessible, the "stair free" pathways are sometimes well hidden. If you need help navigating to the RUB conference center please get in touch with us ahead of time so we can send someone to the subway station to show you the way.

Accommodation

 

There are a variety of accommodations available in Bochum.

Here you will find a partial list of hotels that have been booked by conference participants in the past.

Please note that we are unable to book rooms for you. Please contact the hotels directly.
