At about 120 participants attended this event, which was hold online.

International Conference on Plasticity, Damage and Fracture, ICPDF 2020, Cancun, Mexico, 3-9 January 2020

Two presentation were given at the ICPDF conference in Mexico, namely, one focusing on Deformation Behaviour of Thermo- Mechanical Fatigue Crack Growth: Captured through advanced non-invasive methodologies (SU) and one comprising Modelling the Influence of Plastic Deformation on Local Material Stiffness to Predict the Crack Growth Behaviour of a Nickel Based Superalloy (UNOTT).

TMF Workshop 2019: 4th International Workshop on Recent Developments in Thermo-Mechanical Fatigue, Berlin, Germany, 13-15 November 2019

Bundesanstalt für Materialforschung und -prüfung (BAM), the HTMTC and DevTMF co-organised the international TMF Workshop 2019 in Berlin, Germany, between 13–15 November 2019. The conference covered areas focusing on experimental data, characterisation of deformation and damage mechanisms, modelling, simulation and prediction, applications and test procedures under TMF. Further, DevTMF organised a panel discussion focusing on TMF crack growth test method as TMF crack growth is still an emerging field unlike TMF crack initiation testing under strain control.

Main aims of the panel discussion were to bring more perspectives to the topic by discussing the DevTMF TMF CG test method development results, and exchange experiences and knowledge as well as to define further actions for standardisation of TMF crack propagation test method. The channel that will be utilised for publication of the local CoP will be via the High Temperature Mechanical Testing Committee (HTMTC).

The consortium gave 5 presentations at the TMF workshop covering development of TMF crack growth experimental method (SU), results from the TMF crack growth round robin testing (LiU), TMF crack initiation mechanisms (LiU), TMF crack growth modelling and isothermal/anisothermal viscoelasticity – viscoplasticity material modeling (UNOTT).


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.


  • 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

Symposium organised and three presentations given at EUROMAT 2019, Stockholm, Sweden, 1-5 September 2019

DevTMF organised a symposium at the international conference EUROMAT 2019 in Stockholm, Sweden, 1-5 September 2019. The related symposium was a part of the Structural Materials focus area called B8: High Temperature Material Characterisation, Testing and Mechanical Properties. Topics of interest included:

  • Mechanical properties of alloys at high temperatures (e.g. fatigue, creep),
  • Thermo-mechanical fatigue (TMF),
  • High temperature deformation and fracture mechanisms,
  • Crack initiation and propagation,
  • Environmental properties (e.g. oxidation, corrosion),
  • Fracture and fatigue,
  • High temperature deformation mechanisms,
  • High temperature damage mechanisms,
  • Interaction between mechanical properties (e.g. creep-fatigue, oxidation-fatigue, overload), and
  • High temperature modelling and prediction.

The consortium gave three presentations covering TMF crack growth testing (SU), analysis of the crack driving mechanisms (LiU) and modelling of TMF crack growth (UNOTT).

DevTMF project meeting with dissemination at Nottingham, 11-12 April 2019

A technical project meeting with all the partners was held at the University of Nottingham between 11-12 April 2019 in conjunction with the High Temperature Mechanical Testing Committee (HTMTC) meeting to support the project’s standardisation activities.

The HTMTC was established in 1982 following a conference held at NPL on ‘Measurement of High Temperature Mechanical Properties of Materials’. The membership of the committee includes experts in the field of high temperature testing drawn from industry, research institutions and universities. The HTMTC operates as Technical Committee 11 (TC11) of the European Structural Integrity Society (ESIS). The HTMTC aims to improve the techniques and procedures used for the high temperature testing of materials, and to disseminate this information to the materials community as a whole.
