Brittle cracking model

B. Rock failure model incorporating physical tensile failure mode ABAQUS provides a brittle cracking model to simulate brittle rock feilure processes (Abaqus, 2003). This material model is selected for the developed procedure as it fulfills the tensile failure rep-...

Film-induced cleavage models. It has been suggested that dealloying and/or vacancy injection could induce brittle fracture. The model assumes that a brittle crack initiates in a surface film or layer and this crosses the film/matrix without loss of speed. The brittle crack will continue in the ductile matrix until it eventually blunts and arrests. Verification of this model needs better understanding of the surface films and brittle fracture.

To explain the mechanism of transgranular S.C.C. in a brass, Newman and Sieradzki have proposed the film-induced cleavage model, according to which a brittle crack that initiates in a thin surface film propagates into the ductile matrix and eventually blunts and arrests, after which the process repeats itself [39, 44, 45].
