The purpose of this work is to build a finite element model and prove its convergence with reality. The model with sufficient accuracy should predict the beginning of the growth of a crack of a given geometry, as well as the trajectory of its growth based on the chosen failure criterion. As a practical application of the model, the problem of the stressed deformed state of the pipeline in the presence of a defect in the weld is considered.
