FATIGUE OF DUCTILE METALS AT RANGES OF STEESS EXTENDED TO COMPRESSION

摘要

The object of the study reported herein was to extend the results of fatigue tests into a field which was previously almost entirely neglected; that is, the field of compression fatigue.nThis relative comprehensive axial fatigue test program involving ranges of stress varying from pure compression to tensile stresses approaching the static ultimate strength. The material selected for study was a fully killed, annealed, structural grade steel.nAn unnotched axial load specimen and a notched axial load specimen with a theoretical stress concentration factor of 2.0 were studied.
