  A comprehensive overview is given of the literature on slip transmission
criteria for grain boundaries in metals, with a focus on slip system and grain
boundary orientation. Much of this extensive literature has been informed by
experimental investigations. The use of geometric criteria in continuum crystal
plasticity models is discussed. The theoretical framework of Gurtin (2008, J.
Mech. Phys. Solids 56, p. 640) is reviewed for the single slip case. This
highlights the connections to slip transmission criteria from the literature
that are not discussed in the work itself. Different geometric criteria are
compared for the single slip case with regard to their prediction of slip
transmission. Perspectives on additional criteria, investigated in experiments
and used in computational simulations, are given.
