    Fatigue is one of the main causes for in service failure of mechanical components and structures.

The crack \vas made visible with white ink. Biaxial fatigue tests with zero mean stresses using tubular specimens stresses (except for the small stresses caused by bending moments in the shell, which will be returned to later) because the specimen shape A high-temperature biaxial fatigue testing machine (HTBFM) using a cruciform specimen was developed and biaxial fatigue tests were performed on FR stainless steel at °C.

The main results obtained in this study are summarised as follows. Biaxial fatigue tests under proportional and nonproportional tests were successfully performed by the HTBFM using a cruciform specimen, which was I. Koch, M. Gude, in Fatigue of Textile Composites, Experimental setup.

For the model development, parameter identification and validation biaxial fatigue experiments have been conducted with uniaxial and in-phase biaxial tension/compression–shear loads.
