ActuatorPart of the load frame of the Series LFV is a double ended, in equal area constructed ac-tuator to generate equal axial force in tension and compression with hydrostatic bearings. The hydrostatic bearings provides extremely low fi ction for the most accurate control and longest reliable lifetime at full ratings. A pre-cision displacement transducer is integrated in the actuators. They are well suited for all types of testing (from static to dynamic) and are known for their excellent fatigue reliabili-ty, accuracy and repeatability. These actuators are the most versatile and by far the most popular solution for all types of the Series LFV

TMF affects a range of components, including train wheels and brakes, aircraft and ship engines, components used in gas turbines for power generation and compressors for gas and oil pipelines.

International Standards

ASTM E2368-04Standard Practice for Strain Controlled TMF-Testing

• This practice covers the determination of thermo mechanical fatigue (TMF) properties of materials under uniaxially loaded strain-controlled conditions. A “thermo mechanical” fatigue cycle is here defi ned as a condition where uniform temperature and strain fi elds over the specimen gage section are simultaneously varied and independently controlled. This practice is intended to address TMF testing performed in support of such activities as materials research and development, mechanical design, process and quality control, product performance, and failure analysis. While this practice is specifi c to strain-control-led testing, many sections will provide useful information for force-controlled or stress-controlled TMF testing.

• This practice allows for any maximum and minimum values of temperature and mechani-cal strain, and temperature-mechanical strain phasing, with the restriction being that such parameters remain cyclically constant throughout the duration of the test. No re-strictions are placed on environmental factors such as pressure, humidity, environmental medium, and others, provided that they are controlled throughout the test, do not cause loss of or change in specimen dimensions in time, and are detailed in the data report.

• The use of this practice is limited to specimens and does not cover testing of full-scale components, structures, or consumer products.

European StandardThe International Organisation for Standardization (ISO) set up a working group to draft a TMF testing standard. Progress towards achieving a balanced document has been hampered be-cause of the lack of pre-normative R&D. The aim of this study is to coordinate EU input to the ISO working group and to provide the technical basis that will enable researchers to defi ne all test-related aspects of the draft standard.
