“…Many researchers apply the eXtended Finite Element Method (XFEM) in their studies to overcome the limitations of FEM in the field of fracture mechanics. Since damage mechanics is mesh dependent, XFEM allows pipeline failure prediction under various loading conditions without refining the mesh closer to the region of interest [26]. Using this approach, the mesh conformance of crack geometry is avoided [27].…”

Conventional pipeline corrosion assessment methods for failure pressure prediction do not account for interacting defects subjected to internal pressure and axial compressive stress. In any case, the failure pressure predictions are conservative. As such, numerical methods are required. This paper proposes an alternative to the computationally expensive numerical methods, specifically an empirical equation based on Finite Element Analysis (FEA). FEA was conducted to generate training data for an ANN after validating the method against full scale burst test results from past research. An ANN with four inputs and one output was developed. The equation was developed based on the weights and biases of an ANN model trained with failure pressure from the FEA of a high toughness pipeline for various defect spacings, defect depths, defect lengths, and axial compressive stresses. The proposed model was validated against actual burst test results for high toughness materials, with a R2 value of 0.99. Extensive parametric study was subsequently conducted to determine the effects of defect spacing, defect length, defect depth, and axial compressive stress on the failure pressure of the pipe. The results of the empirical equation are comparable to the results from numerical methods for the pipes and loadings considered in this study.

“…In this paper, our intent is not to provide an exhaustive overview of the XFEM since many such reviews are already available. [32][33][34][35][36][37][38] Rather, the aim here is to provide extensive report on XFEM application to different kinds of problems in the form of case studies, as they were tackled in the scope of activities of the Belgrade school of XFEM simulation. Such an overview was already presented in a short form, 39 covering the period 2011-2018.…”

Numerical simulation of fatigue crack growth (FCG) is presented, based on the application of the extended finite element method (XFEM). Couple of case studies are presented, as a review of recent experience of the Belgrade school of XFEM simulations, established at the Faculty of Mechanical Engineering. Case studies comprised Charpy specimen with initial crack at the notch tip, oil rig pipe with an axial surface crack, pressure vessels with a crack at the welded joint with connecting pipe, turbine shaft with a crack at the transition radius, optimization of a wing spar in respect to FCG, the effect of mesh size on fatigue life estimation of a stringer panel, fatigue life estimation of wing‐to‐fuselage connecting lug, geometry effect on fatigue life of orthopedic plates and fatigue life of hip implant. Based on these case studies, XFEM is discussed in respect to its accuracy and efficiency. It is concluded that XFEM is a versatile tool for simulation of FCG, providing an excellent option for precise and reliable fatigue life of a cracked component.

“…Pipelines experience large plastic deformations leading to failure due to various movements under ground within harsh environment in the arctic and subarctic regions [2,3]. There exist several methods to characterize and predict failure in pipelines such as experiments, analytical methods, finite element method (FEM) and extended finite element method (XFEM) [4]. Among these methods, XFEM has been found the most efficient tool to simulate the full-scale and small-scale tests for pipeline materials to characterize such a failure [4].…”

It is generally accepted that the fracture strain is dependent on geometry/constraints in metals. However, the current available implementation of XFEM assumes a fixed fracture strain criterion independent of the constraints. The objective of this paper is to develop and implement a variable fracture strain criterion in XFEM that is capable of predicting a wide range of fracture conditions in X65 pipeline steels with various crack tip constraints. Various small-scale tests with different out of plane constraints obtained from the literature were simulated using the XFEM in ABAQUS software. These tests included smooth bar, notched bar, single edge notch tension (SENT), and single edge notch bending (SENB) tests. For each test, the value of the maximum principal strain (Maxpe) as a fracture initiation criterion in the cohesive zone model (CZM) in XFEM framework was varied while keeping the fracture energy constant until the model was able to accurately replicate the reported experimental results. For each test, the crack tip constraints were characterized and the stress triaxialities and Lode angle parameters at the onset of fracture initiation were calculated from the models. The results allowed expressing the fracture strain as an explicit function of stress triaxiality which was then implemented in ABAQUS XFEM using UDMGINI subroutine. For the sake of comparison, the tests were simulated in finite element method (FEM) using a similar damage initiation model namely, the Johnson-Cook (J-C) model. A single model in XFEM was able to accurately replicate the experimental observations for all specimens and compared well to experiments in the way simulated by FEM damage model. However, it was observed that XFEM was more suitable to simulate specimens with pre-existing cracks such as in SENT and SENB tests since the crack grew through elements when mesh refinement was not required around the crack tips. Lastly, the simulated results were found to be less mesh sensitive in XFEM than in FEM damage models.
