title = "Plastic limit pressures of circumferential cracked pipe bends",
abstract = "This paper provides limit pressures for circumferential cracked pipe bends, resulting from systematic, small strain FE limit analyses using elastic-perfectly plastic materials. Circumferential through-wall and constant-depth part-through surface cracks at both extrados and intrados are considered, but the length of circumferential through-wall cracks is limited to 50% of the circumference. It is found that limit pressures of pipe bends are not affected by the presence of the circumferential surface crack, unless it is sufficiently deep and long. Moreover limit pressures for circumferential surface cracked pipe bend decrease almost linearly with increasing a/t and . Based on FE results, approximate closed-form solutions for limit pressures are given.",
