Relation between (open quotes)failure(close quotes) and (open quotes)damage(close quotes). Quarterly report, April--June 1970

摘要

Results of this investigation show that the 'damage point' derived from an interrupted tensile test does not correspond to the 'failure point' obtained from a creep test. It may correspond to the first transition point in constant-stress creep tests. The 'damage point' is obtained from repeated tensile stress cycles of ever-increasing intensity; when the stress-strain curve no longer follows parallel paths, the 'damage point' has been reached.
