Modeling and optimization of a cracked pipeline under pressure by an interactive method: design of experiments

This work is a contribution to the field of gas transport as well as the safety of pipelines and stations under pressure, to better understand this study, we will use experimental results of two tensile tests of two pipelines (APIX52, APIX60), her thickness is 5.1 and 7.1 mm respectively and outside diameter is 508 mm. Using code abaqus calculation, we will simulate two pipeline with presence of a semi-elliptical crack (0.4 mm $$\times $$× 0.8 mm), while varying the parameters thickness (5.1 and 7.1 mm), yield strength (359, 414 MPa) and pressure (7.1, 10.4 MPa) to calculate J integral in each case. Once the values of J integral calculated and compared to other authors, we will exploit these results with the MODDE 5.0 software in order to provide an analysis based on the DOE method to determine the influence of each parameter on the J integral, and see which is the most influential and Secondly proposed a model that represents the analytical part of this method and give confidence interval of each parameter.
