- Description
- The first 3D burst capacity models are developed herein. The development of the 3D burst capacity models is a major advance from the past 50 years, during which numerous 2D bursting failure prediction models (so-called burst capacity models) were developed. These 2D models have become more complicated and less practical while trying to reduce their relatively low accuracy and poor stability in their burst pressure predictions. The 3D models bring simplicity and accuracy together by employing a new parameter, the volume of the defect, to estimate, accurately, the burst pressure of steel pipelines with localized defects of complex morphology. For development and validation of these new models two sets of numerical simulations and a series of innovative full-scale burst capacity tests were carried out.
