Webb16 jan. 2001 · In this paper we review the fracture mechanics of smooth cracks in micropolar (Cosserat) elastic solids. Griffith’s fracture theory is generalized for cracks in micropolar solids and shown to have two possible forms. The effect of fractality of fracture surfaces on the powers of stress and couple-stress singularity is studied. We obtain the … Webb11 apr. 2024 · The classical Stefan problem, concerning mere heat‐transfer during solid‐liquid phase transition, is here enhanced towards mechanical effects.
