“…The unidirectional tensile stress cr can be resolved into o1 and cr2, which are perpendicular and parallel to the crack plane, respectively. If crl is applied to the micro-crack, according to (2), ( 3 ) and (4), CT,, and oyy always decrease due to the second term effects in (2), and cxy = 0 when 0 = 0 (a = 45'). This indicates that it is not easy to nucleate and grow in modes I and I1 under the action of a stress el.…”

“…The stress rate is calculated using Eqs. (6) and (7), where m σ is the simple stress rate until the maximum stress amplitude is reached after the dynamic stress starts to increase, and rm σ is the simple stress rate until the maximum stress amplitude is reached after the impact load is applied. K 0a,σ and K 0a,ε , which are used to evaluate the behavior of the impact strength in terms of the stress rate, are also the same.…”

“…Early work featured one-way [9][10][11][12][13][14] or two-way [15][16][17][18][19] coupled methods, in which displacement fields established at the interface between continuum and atomistic regions were computed either from sophisticated interfacial conditions or from initial conditions derived from continuum elasticity theory. Increases in computing power permitted more realistic two-way couplings, whereby atomistic fields were permitted to affect the far-field elastic continua through the latter's discretization with finite elements [20][21][22][23]. Such improvements in the coupling algorithms enabled description of dynamic crack growth [21].…”

“…Increases in computing power permitted more realistic two-way couplings, whereby atomistic fields were permitted to affect the far-field elastic continua through the latter's discretization with finite elements [20][21][22][23]. Such improvements in the coupling algorithms enabled description of dynamic crack growth [21]. These approximations were also prudent at the time as uninteresting effects in nearly homogeneously deforming regions far from defects could be disregarded and because of the limitations of then available computing resources.…”
