Lower Bound Net-Section Limit Loads for Circumferential Part-Through Surface Cracked Pipes under Combined Pressure and Bending

  • 발행 : 2007.05.30

초록

This paper provides plastic limit loads of pipes with constant-depth, circumferential part-through surface cracks under combined pressure and bending. A key issue is to postulate discontinuous hoop stress distributions in the net-section. Validity of the proposed limit load solutions is checked against the results from three-dimensional (3-D) finite element (FE) limit analyses using elastic-perfectly plastic material behavior.
