Abstract The phase-field fracture (PFF) approach has achieved great triumphs in modeling quasi-static fracture.
Nevertheless, its reliability in serving dynamic fractures still leaves something to be desired, such as the
prediction of the limiting crack velocity. Using a pre-strained fracture configuration, we discovered a
disturbing phenomenon that the crack limiting speed identified by the dynamic PFF model is not related to
the specific material, which seriously deviates from the experimental observation. To ascertain the truth,
we first ruled out the correlation between the limiting crack velocity on the phase-field characteristic scale
and external loading. Afterward, by More >
