Generalization of the Leonov‐Panasyuk‐Dugdale δ c cohesive model applicable not only for cocks tips but also for any internal or boundary point is described. These models are interpreted also as non‐local strength conditions and can be used for description of strength small scale effects, for stress fields with stress singularities other than the usual crack tip square root singularity (e.g. for corner points), for bodies with smooth and singular stress concentrators.
