announce holding of the

Workshop on Computational Fatigue Analysis 2013
&
The 5th PragTic Users' Meeting

Hotel Rytířsko, Rytířsko, Jamné 156, Czech Republic

October 21-23, 2013

Goals of the Meeting

  • Provide basic know-how on fatigue damage evaluation on mechanical parts to designers and computational analysts, including a description of methods used for assessing cyclic service loading under simple and complex loading.
  • Introduce and present ability of PragTic to serve as a post-processor of an FEA, including demonstrations of solutions, in order to find new individuals and companies interested in using and further developing PragTic.
  • Increase awareness of FatLim and FinLiv databases and projects related to them.
  • Inform about the latest news concerning the FADOFF consortium development.
  • Provide the interim results of the FADOFF campaign on validating various fatigue method and fatigue solvers with available experimental data.

PragTic is a freeware tool focused on fatigue analysis based on FEM data. You can find more details concerning this project on www.pragtic.com, where the program can be downloaded.

FatLim & FinLiv MySQL/PhP databases are accessible to any visitor through Internet (http://www.pragtic.com/fatlim.php and http://www.pragtic.com/finliv.php). The main reasons for creating the databases are to

  • preserve knowledge on experiments concerning fatigue limits under uniaxial and multiaxial loading;
  • validate various computational methods on collected data and present all results;
  • provide as far as possible equal access to this data to all researchers and engineers who need it for their work.

Recently, their transfer to the FADOFF consortium website (http://www.fadoff.cz) was initiated and has to be mostly finished by the time, when the workshop will happen. This transfer includes not only a redressal procedure, but a broad evaluation of primary experimental sources as well.

FADOFF is an acronym for the Fatigue Analysis Documentation OFFice (http://www.fadoff.cz), which is a consortium of the CTU in Prague, Evektor, VZÚ Plzeň and VŠB-TU Ostrava aimed at analyzing the situation in the computational methods for:

  • multiaxial fatigue analysis
  • fatigue prediction on notched structures

FADOFF also takes over the future development of PragTic and related web applications.

Program Topics

The invited educational lectures concern:

  • Methods, resources and tools for obtaining cyclic and fatigue material parameters - Robert Basan, University of Rijeka
  • Practical use of genetic algorithm for deriving parameters of more complex fatigue models - Marina Franulović, University of Rijeka
  • Advanced life prediction of TMF treated components - Patrik Huter, Montanuniversität Leoben
  • Some pitfalls of S-N curve fits and rough construction of its tolerance bands - Jan Kohout, Univerzita obrany
  • Textural fractography of fatigue fractures - Hynek Lauschmann, Faculty of Nuclear Sciences and Physical Engineering of the CTU in Prague
  • From Neuber's fictitious notch concept to the averaged SED on a control volume - Filippo Berto and Paolo Lazzarin, University of Padua
  • Thermo-mechanical fatigue - damage operator approach - Marko Nagode, University of Ljubljana
  • Multiaxial fatigue - Jan Papuga, Faculty of Mechanical Engineering of the CTU in Prague & Evektor, spol. s r.o.
  • Practical aspects of fatigue prediction - Jan Papuga, Faculty of Mechanical Engineering of the CTU in Prague & Evektor, spol. s r.o.
  • Basics of fatigue and fatigue prediction - Milan Růžička, Faculty of Mechanical Engineering of the CTU in Prague

Each invited lectures is timetabled for 1-2 hours. For the first time, the organizers decided to prepare a part of the lectures in the first day concurrently. This decision was taken because we anticipate that many participants of the workshop could be annoyed to hear again and again the basics of fatigue prediction, on the other hand, this topic cannot be avoided because of the newcomers. The fatigue basics will be thus taught simultaneously with two lectures on thermo-mechanical fatigue.

More detailed information about the programme will be subsequently published in the section Program.

Conference Location and Accommodation

The meeting is held in Hotel Rytířsko, a reconstructed manor house nearby Jihlava, just 800 m from D1 highway in between Brno and Prague. The standards of the hotel concerning accommodation as well as of the conference halls are very good. Once the lectures are over, you can use the swimming pool there, play bowling, or just hike around in the beautiful countryside of highlands. The close vicinity to three UNESCO sites (Třebíč, Telč and Zelená Hora near Žďár nad Sázavou) makes it an interesting destination for any travels before or after the conference.

The conference fee includes full board (without drinks). The price for the accommodation is not included. Check the Payment section for more detailed information.

Attendance Fee

The fee is set in two versions.

The Early Bird rate is available to all who will pay before September 6, 2013:

  • students - 130 EUR
  • other participants - 230 EUR

The regular rate is for all participants who settle their payment after September 6, 2013:

  • students - 150 EUR
  • other participants - 270 EUR

The fee includes meals without breakfests (these are included in the accommodation fee of the hotel), a CD-ROM with presentations, and workshop attendance.

Members of the Czech Society for Mechanics pay 10% less.

Details concerning payment of the attendance fee are presented in the Payment section of the conference website.

Conference Language

English language is the official language of the lectures.

Application

You can register to the meeting in the Application section. Note please that there is the early bird rate established and also that the members of the Czech Society for Mechanics are expected to pay 10% less.

Further Details

  • Up-to-date information concerning e.g. the time schedule and transport to the location will be published subsequently in new sections created in the bottom right-hand space on the conference web-page.
  • The training in using PragTic will be organized at the end of the 5th PragTic Users' Meeting, according to the demand of participants. Please contact us on papuga@pragtic.com as soon as possible, if you are interested in taking part. The course will last approximately 4 hours. Participants in the training lessons are asked to bring along their own laptops.
