“…In Zuo et al, concerning brittle materials [ 3 ] where the authors’ own subroutine was used, the influence of the arrangement of sedimentary rock layers on the fracture propagation angle was investigated. Studies have been conducted on the fatigue of the surface layer of the material under the influence of cyclic friction [ 4 , 5 ]. In most other studies, the cracking of steel [ 6 , 7 ], composites [ 8 , 9 ], or polymers [ 10 ] has been investigated.…”

This paper describes a method of predicting the direction of crack propagation implemented by user subroutines in the Simulia-Abaqus FEA system with the use of the extended finite element method (X-FEM). This method is based on displacements and stresses according to Westergaard’s solution of Griffith’s crack problem. During the calculations, in each crack increment, the algorithm reads the stresses and displacements in the model around the crack tip, calculates the criterion values at the read points, reduces them to a unit distance from the crack tip, fits a polynomial to these points, and finds the minimum of the function closest to the last propagation angle. The algorithm also decides when the crack grows, depending on a chosen criterion. Four criteria have been implemented to predict the direction of failure propagation: the maximum principal stress criterion, the Ottosen–Podgórski criterion, the new criterion described here based on the minimum component values of the displacement vector, and the maximum circumferential tensile stress (MTS). These criteria were verified in two tests: the three-point bending test of the notched beam and the anchor pull-out test. For these tests, the criterion built into Simulia Abaqus does not correctly define the crack path, which causes the crack propagation direction to “rotate” when simulating the fracture. The criteria developed here, in most cases, determine the crack path and the maximum force very well compared to real laboratory tests.

“…There are many studies in the literature that deal mainly with the initial phase or crack formation. Pereira et al (2018) conducted a study on the prediction of fretting fatigue crack initiation location and direction using cohesive zone model, where they concluded that the model used can accurately point out where a crack appears, but were unable to accurately provide its orientation using stress criteria.…”

Purpose This study aims to develop a numerical identification and characterization of crack propagation through the use of a new optimization metaheuristics called Lichtenberg optimization. Design/methodology/approach The damage-identification problem is treated as an inverse problem, which combines finite element methods with intelligent computational methods to obtain the best possible response. To optimize the objectives, the Lichtenberg algorithm is applied, which includes concepts of random cluster growth in nature. Findings The simulations show that it is possible to determine the Lichtenberg spectrum algorithm a part of the structure to be removed and replaced in this case to stop the propagation. Originality/value The results show a very good crack identification in plates-like structures using the Lichtenberg algorithm (LA) based only in strain fields. Although many studies have reported on damage-identification-based optimization methods, very few have focused on the crack tip modeling and LA as the main solver.

“…Particularly, crack propagation and fracture failure were simulated by extended finite element method (XFEM) (Giner et al, 2008, 2009, 2011; Martínez et al, 2017). A cohesive model with secondary traction separation criterion was used for predicting the initial position and propagation direction of cracks with high accuracy, but the life prediction was not satisfied (Pereira et al, 2018). A method for averaging normal and shear stresses along the critical point was developed for the expected crack propagation direction (Araújo et al, 2017).…”

For fretting fatigue, micro-slipping often causes initial micro-cracks in the contact surfaces, which gradually propagate and eventually result in fracture failure. However, it is difficult to directly observe and measure the crack initiation and propagation processes of single-lap bolted joints due to the obstacle of testing technique. Therefore, this article presents an elastic analysis–based method, in which the total fretting fatigue lifetime is divided into initiation life predicted by continuum damage mechanics and propagation life calculated by SEAM Tool in combination with Paris’s law. Since the initiation life model implicitly reflects the result of damage process, one can directly calculate the initiation life based on the elastic stress analysis. The predicted fretting fatigue life, initial crack location, and propagation path are in reasonable agreement with the fretting fatigue test and scanning electron microscope observation results. In addition, it is found that among the main factors affecting fretting fatigue of steel single-lap bolted joints, the initial life is affected by cyclic stress, friction coefficient, and tightening torque, and the propagation path is mainly influenced by tightening torque.
