Abstract:

Fatigue tests of 7075-T6 aluminum alloy under synchronous pulsating triaxial stresses were performed with three different values of the intermediate principal stress. Thick-walled tubes were subjected to internal pressure pulse axial stress such that the state of stress at the inner surface was as follows in the first case the intermediate principal stress was a compression equal to the internal pressure in the second it was a tension equal to the internal pressure and in the third it was a tension equal to the hoop stress at the inner surface. Results showed no effect of the intermediate principal stress. Author
