Computational Assesment of Remaining Load Carrying Capacity of Pipes with Areal Surface Defects
Original language description
This paper reports on two criteria for burst pressure prediction of pipe with the areal surface defect. The criteria deal with defects in internally pressured pipes without significant global bending loads. On the basis of the experimental analysis relatively simple methodologies of prediction were designed. They are based on finite element (FE) analysis. Concept of presented methodologies is based on similarity of stress, strain and material state when plastic collapse starts in the defect domain. Thesimilarity is expressed in terms of simple one-parametric criteria: (i) geometry and topology of the domain at which the plastic state of material is reached, (ii) amount of specific energy dissipated by plastic deformation in the regions, where the ratio of energy dissipated by plastic deformation compared to elastic stress energy is too high. Calibration of these methodologies is based on burst tests of DN800 pipes made of X60 steel with artificial defects.
