In an earlier publication (Engng Fractive Me& 32,249-258 (1989)) a stochastic fracture criterion was derived for a brittle body with population of crack-like defects under abritrary triaxial load. In this work the above criterion was applied to a nonuniform distribution of defect orientations, whose
In the case of relatively brittle structural materials, linear fracture mechanics provides an analysis basis for testing and control of fracture strength. Standardized methods of crack toughness testing are available only for metals which can be pre-cracked by fatigue. Hence, further work on this t
Surface-cracked specimens of several thicknesses of 7075-T65 I and 7075-T6 aluminum were tested in uniaxial tension. For thicknesses t less than 0.25 in., the gross fracture stress of of 7075-T65 I AI was empirically related to flaw size by the following expression: where cull is the ultimate stren
