4th Workshop on Thermo-Mechanical Fatigue International TMF-Workshops

Scope

Components in the Aerospace, Power and Automotive engineering sectors are frequently subjected to cyclic stresses induced by thermal fluctuations and mechanical loads. For the design of such components reliable material property data are required which need to be acquired using well accepted and reproducible testing procedures. The 4th TMF-Workshop will be held in conjunction with the final meeting of the research project DevTMF which deals with TMF crack growth and is funded by the European Commission under Horizon 2020 and Clean Sky 2. The intention of the present event is to continue the exchange of knowledge in the TMF regime. It provides a forum to present and discuss all recent developments in the field of thermo-mechanical fatigue.

The European DevTMF Project

In this project the experimental techniques of TMF crack growth and the predictive tools to characterize the thermo-mechanical fatigue behaviour and damage mechanisms are being developed in two Nickel-base superalloys. It has 3+1 project partners, a run-time of 48 months and ends in January 2020. The partners are Linköping University Sweden, Swansea University, UK, Nottingham University, UK and Rolls Royce plc, Derby, UK. The achievements of the project will be presented on the workshop.

Topics

  • TMF crack growth measurement
  • TMF life and crack growth models
  • TMF of steels, cast irons, aluminum-, titanium-, nickel base and other alloys
  • Cyclic stress strain behaviour at TMF
  • Comparison of TMF and LCF life
  • TMF and superimposed HCF
  • TMF and creep interactions
  • TMF and environmental interactions
  • Multiaxial TMF
  • TMF of coated materials
  • TMF and thermal fatigue of components
  • TMF damage mechanisms
  • Interpretation of TMF data
  • Force or strain controlled TMF testing
  • Service-cycle TMF testing
  • TMF test procedures and standardization
  • Applications

Target group

The TMF Workshops are aimed at engineers, scientists and technical staff of research institutes and industry who have an interest in the numerous aspects of thermo-mechanical fatigue.

Invitation and call for papers

Attendees who wish to give an oral or poster presentation are invited to submit a one-page abstract (A4) containing title, list of authors and the outline of the intended contribution until May 31st, 2019. One figure may be included. Authors will be notified of abstract acceptance until July 31st, 2019. A book of abstracts will be available during the workshop.

Publication

It is intended to publish papers of the Workshop in the International Journal of Fatigue. The full papers will be due at the conference. After the peer review, the papers will be published in a virtual special issue of the journal which can be downloaded at www.sciencedirect.com.

History

International Workshops on Thermo-Mechanical Fatigue were successfully held at BAM in 2016, 2011 and 2005. The first TMF-Workshop was held on the occasion of the development of a European Code of Practice for strain-controlled TMF testing. It brought together approx. 70 European and international experts. The 2nd TMF-Workshop was successful as well with approx. 100 international participants. From 2012 to 2015, a Code of Practice for Force Controlled TMF testing was developed by a European group of experts. The paper was presented and discussed on the 3rd International Workshop on Thermo-Mechanical Fatigue in 2016. The workshop was attended by approx. 90 attendees from 17 countries.
