Stress intensity factors of partially compressed centrally cracked disk with frictional crack surfaces

Abstract This work analytically calculates mixed-mode I/II stress intensity factors for an inclined central frictional crack in a Brazilian disc partially compressed with uniform pressure. Wide-range controlling parameters are invoked. The analyzed include the pressure angle, relative length, inclination, and friction coefficient between two surfaces. For discs, there exists critical angle at which any will experience pure II loading. is not affected by decreases as length increases. A of becomes inactive once exceeds another value angle. or/and handling surfaces short cracks simplified. analysis defines conditions to have (1) opened (2) sticking. close agreement achieved relevant findings previous investigations. present results do exist literature valuable solving fracture mechanics problems significance relation path cracked brittle materials.
