The discontinuous model is a model in which the discontinuities inside the continuum are taken into consideration. We showed, in the first report, that this model can be specialized so as to correspond with the elastic-plastic crack models in which the continuous distribution of dislocations is assumed. In this paper, the finite element formulation for the discontinuous plane using isoparametric elements is presented, and we show that we can treat more generalized dislocation models by applying a general constitutive equation to the discontinuous plane. Further, various kinds of elastic-plastic crack models by introducing the discontinuous planes are discussed, and, through the corresponding finite element analyses, their applicability is considered.
