The subject of this paper is to analyze the stress concentrations near the tip of a crack traversing a plate in uniform tension or shear. A method is presented to construct the transient interval at crack tip where both the crack opening displacement and the finite stress concentrations appear. The stress functions of this type are more suitable than Dugdale's assumption to analyze the crack problems contained in materials such as concrete or rock. Several numerical examples are shown to represent the possible stress distributions and crack opening displacement shapes along the crack line.
