Abstract
AbstractTi‐6Al‐4V plates were machined simultaneously to achieve the reduced section of specimens with a wire‐cut electrical discharge machine (EDM). Geometric shape errors due to the cutting path deviation were discovered on many specimens after the final manufacture. High‐cycle fatigue tests were carried out on these symmetrical and asymmetrical shaped specimens. Probabilistic treatment was used to examine the occurrence probability of one or two cracks, and the fatigue failure mechanisms were investigated using scanning electron microscope (SEM). The objective of this work was to highlight the impact of the geometric size deviation on fatigue life and crack growth.
