Tagungen

• Scope:
  

  The Symposium wants to address one of the open challenges in computational mechanics: the prediction of damage, crack growth, and the extent of fragmentation in multi-field problems. In a multifield environment, the modeling of the material is per se demanding; in addition, the intricate and non-regular structure of cracks renders numerical simulations of cracking bodies extremely difficult. Beyond well established and popular methods based on cohesive zone and extended finite elements that advanced remarkably computational fracture mechanics, recently several innovative approaches have emerged, such as phase-field fracture, eigenfracture, eigenerosion, and peridynamics. These approaches are characterized by a regularization of the evolving crack boundaries which requires the inclusion of a small but finite length scale. This length scale arouses new questions and doubts, especially when multi-physic problems are considered. We would like to illustrate and compare different computational strategies for multi-field fracture problems, opening a forum to discuss new horizons and new perspectives of computational fracture research. The symposium will address the most advanced aspects of the research in the field, from specific methods of choice and numerical strategies to theoretical developments of constitutive modeling in a multi-field setting. Pioneering discretization methods for the solution of failure phenomena in coupled non-linear environments at different length scales and affected by uncertainty will be especially welcome.

• Special occasion:
  

  Within the symposium, we want to celebrate the 70th birthday of Professor Michael Ortiz, who has been at the forefront of the research in these endeavors as well as in many others.

• Update (Oct 28):
  

  Dear All,
  on October 28 the federal German government has enacted a new lockdown and tightened restrictions pertaining to travel and meetings. In view of these developments, we must conclude at this time that the symposium is no longer viable and, with deep regret, we are forced to call it off. We are grateful to all of you who have steadfastly supported the symposium despite these difficult times.

  In the name of the organizing committee,
  Kerstin Weinberg, Anna Pandolfi, Michael Ortiz

• About Corona:
  

  If you come from a risk-areas country (1), you must present a medical certificate, which must not be older than 48 hours. The 48-hour period begins at the time the test result is approved and ends at the time of entry into the Federal Republic of Germany.

  In the current regulation of the state of North Rhine-Westphalia - the location oft he Physikzentrum - there is no regulation for travelers from no-risk-areas countries or inner-German risk areas.

  The hygiene concept of the Physikzentrum has been practiced since July and has proven itself. The short version: compulsory masks everywhere except in the lecture hall and at the dining table. For more details see the file attached. All participants are accommodated in single rooms, unless a double room is explicitly requested.

• Scientific Topics

Topic of the IUTAM symposium is the computational prediction of damage, crack growth, and the extent of fragmentation in solids.

Recently, research in computational fracture mechanics has advanced remarkably, typically using cohesive zone models and extended finite elements. Beyond these well established and popular methods, several innovative approaches have emerged, such as phase field methods, eigenfracture, eigenerosion, and level-set methods. These approaches are characterized by a regularization of the evolving crack boundaries with an additional small but finite length scale. This length scale arouses new questions and doubts, in particular concerning multi-physic problems.

The aim of the IUTAM symposium is to draw a comparative overview of different computational strategies for multi-field fracture problems by illustrating the most innovative -non necessarily the nowadays most popular- techniques. We would like to open a forum to discuss new horizons of multi-field fracture mechanics covering several aspects of research on computational fracture, starting from specific methods of choice and numerical strategies to theoretical aspects of constitutive modeling in a multi-field setting. Particular emphasis will be laid on pioneering discretization methods for the solution of coupled non-linear problems at different length-scales.

The participation at the IUTAM Symposia is by invitation from the Scientific committee only.

• Phase Field Modelling
  

  Phase field models have been in the focus of research in applied mathematics and mechanics in recent years. Due to the multiple applications in coupled problems, phase transitions, and fracture the GAMM activity group on Phase field modelling was installed at the annual GAMM meeting 2013, in Novi Sad, Serbia. The intention of the activity group is to bring together expertise from mathematics, mechanics and materials science, to improve the understanding of phase field approaches, to analyse the models analytically, and to devellop improved numerical schemes.
  The activity started its actvity in the summer of 2013 with a kick-off meeting in Frankfurt.

We thank all the participants for their valuable contributions. The friendship and fellow-feeling felt during the symposium inspired the idea to collect the presentations of some of the present researchers in a special book. Our choice was to organize a book as part of the series Lecture Notes in Applied and Computational Mechanics (LNACM), entitled Innovative Numerical Approaces for Multi-Field and Multi-Scale Problems. It will appear at Springer in July 2016.

How to get there?

• The venue is a Castle and can be reached at best by car. Next regional train station is Finnentrop. Main train stations nearby are Cologne, Dortmund or Hagen. The next airports are Cologne Bonn Airport and Frankfurt Airport. Neither from Cologne nor from Frankfurt to Attendorn are direct train or bus connections. There will be, of course, taxis. We think to organize a 'shuttle service' in a sense, that we pre-book a taxi or minibus which collects several people of the symposium to share the costs. If you are interested, please send us your time of arrival at: IUTAM(at)uni-siegen.de
• If you prefer to go by train, you may find connections at bahn.de; we would recommend to go to Finnetrop and then take a taxi.
• If type into google maps 'Burghotel Schnellenberg' you find a map of the location.

Some more details:

• The symposium room in the conference venue will be equipped with a Computer (Windows;VGA), LCD projector, laser pointer and microphone.

• Poster size should be A0 (portrait, i.e., 84x119cm) or any other format with at most 90cm width.

• A get together with medieval music and a corresponding meal is planned in the evening of Tuesday September 2nd, opened to all symposium participants.

We thank our colleagues who accepted to attend the IUTAM on the occasion of M.Ortiz’ 60th birthday. For an enjoyable stay we ask you for an "all inclusive" conference fee. The fee includes symposium material, lodging with full meals at the castle Burg Schnellenberg, a featured Medieval Social Event, and a book of Abstracts of the symposium contributions.
