Description

The validity of Palmgren-Miner rule is verified for working life between about 500 and 1,000,000 cycles for two damages: one corresponding to complete rupture of smooth test piece and the other corresponding to initiation of a fatigue crack in a high stress area. Material studied is a stainless steel Z3CND17-12 (AISI 316) used in nuclear industry. Validity of the rule is better verified in the case of small cracks than for a smooth sample. (15 references are given)

Abstract (French)

La validite de la regle de cumul lineaire de Palmgren-Miner a ete examinee dans le domaine des durees de vies comprises entre environ 500 et 1 000 000 cycles pour deux types de dommages: - l'un correspondant a la rupture complete d'eprouvettes lisses, - l'autre correspondant a l'amorcage au sens macrographique d'une petite fissure de fatigue dans une zone a forte concentration de contrainte (zone singuliere). Le materiau etudie est un acier inoxydable Z3CND17-12 (AISI 316) utilise dans la construction nucleaire. L'analyse des resultats montre que cette regle est mieux verifiee dans le cas ou le dommage est defini par l'apparition d'une petite fissure en zone singuliere que dans le cas d'une eprouvette lisse
