Workshops 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 test procedures for thermo-mechanical fatigue (TMF) loading. Available materials TMF property data are limited so that there is a need for further TMF data generated by TMF testing. The TMF behaviour of materials is often desired to be simulated in models which describe the cyclic stress-strain behaviour, the fatigue life and the cyclic crack growth behaviour. There is a continuous need for the development and amendment of such models. Models can be validated by using materials in industrial applications which are subjected to TMF loading.

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.
