Embedded crack model. I: Basic formulation. II: Combination with smeared cracks. (English) Zbl 1013.74068
From the summary: The paper describes a triangular element with an embedded displacement continuity that represents a crack. The constitutive model is formulated within the framework of damage theory, with crack closure effects and friction on the crack faces taken into account. Numerical aspects of the implementation are discussed. In part II, the embedded crack approach is combined with the more traditional smeared crack approach.
