Abstract: | The purpose of the investigation reported here was to examine experimentally the transition behavior of a short crack in detail
using surface-crack measurements with a traveling microscope and micromeasurements obtained by scanning-electron microscopy
(SEM). The cyclic growth and transition of initial part-through cracks into through the thickness flaws are documented through
experiments by using compact-type specimens fabricated from 7075-T6 aluminum, 2024-T3 aluminum, and mild-steel material, with
a keyhole notch.
