We showed that an ability of the initial crack to propagate in supershear regime can be predicted with use of the empirically derived dependence of the geometrical criterion of sub-Raleigh-to-intersonic transition on material and crack parameters.en530 Physiknumerical analysisshear cracksvelocityArticle1551-7616
