Abstract

Low-cycle fatigue tests of aluminium were interrupted in order to remove surface roughening and superficial cracks produced by prior loading. Depending on the frequency of intermittent polishing and the strain level considerable increases in endurance life were observed.

Nomenclature

Δɛt

total strain range

Δɛp

plastic strain range

Δɛe

elastic strain range

Np

Nmp

the number of cycles at which the last intermittent polishing action is performed in addition to preceding ones in every 50 cycles (multi-step tests)

Npf

the endurance life in the case of intermittent polishing (single- or multi-step tests)

Nf

the endurance life without intermittent polishing
