      abstract     = {The failure of frictional interfaces — the process of
                      frictional rupture — is widely assumed to feature
                      crack-like properties, with far-reaching implications for
                      various disciplines, ranging from engineering tribology to
                      earthquake physics. An important condition for the emergence
                      of a crack-like behavior is the existence of stress drops in
                      frictional rupture, whose basic physical origin has been
                      recently elucidated. Here we show that for generic and
                      realistic frictional constitutive relations, and once the
                      necessary conditions for the emergence of an effective
                      crack-like behavior are met, frictional rupture dynamics are
                      approximately described by a crack-like, fracture mechanics
                      energy balance equation. This is achieved by independently
                      calculating the intensity of the crack-like singularity
                      along with its associated elastic energy flux into the
                      rupture edge region, and the frictional dissipation in the
                      edge region. We further show that while the fracture
                      mechanics energy balance equation provides an approximate,
                      yet quantitative, description of frictional rupture
                      dynamics, interesting deviations from the ordinary
                      crack-like framework — associated with non-edge-localized
                      dissipation — exist. Together with the recent results
                      about the emergence of stress drops in frictional rupture,
                      this work offers a comprehensive and basic understanding of
                      why, how and to what extent frictional rupture might be
                      viewed as an ordinary fracture process. Various implications
                      are discussed.},
