The Effect of the Intermediate Principal Stress on Triaxial Fatigue of 7075-T6 Aluminum Alloy,
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)
