“…The aim is to predict numerically the observed crack paths. The analysis of a 2D model of the physical tests is carried out using the X-FEM implementation developed by the authors [7][8][9]. The implementation is performed as a user's subroutine in the commercial code ABAQUS and can take into account crack face contacts along the loading cycle, which has been proved to be essential for the correct crack prediction.…”

In this work, the orientation and propagation of a crack in a fretting fatigue problem is analyzed numerically and correlated experimentally. The analysis is performed using a 2D model of a complete-contact fretting problem, consisting of two square indenters pressed onto a specimen subjected to cyclic fatigue. For the simulation, we use the extended finite element method (X-FEM), allowing for crack face contact during the corresponding parts of the fatigue cycle. The problem is highly non-linear and nonproportional and an orientation criterion is introduced to predict the crack direction in each step of the crack growth simulation. It is shown that the proposed criterion predicts crack orientation directions that are in good agreement with those found experimentally, in contrast to the directions found by application of conventional orientation criteria used in LEFM, such as the MTS criterion.

“…Nistor et al [40] implemented the XFEM in an explicit FEM code for dynamic crack analysis using an object oriented framework. Giner et al [25,26] proposed an Abaqus implementation of 2-D XFEM aimed at the simulation of fretting fracture crack propagation. We can also mention the Abaqus implementations of Lua et al [36] for curvilinear crack growth and life prediction based on XFEM; Xu and Yuan [64,65] for mixed-mode fatigue crack growth in quasi-brittle materials; and the XFEM toolkit of Shi et al [53] for automated crack onset and crack growth prediction.…”

Kim, D J.; Duarte, C A.; and Eason, T, "Analysis of three-dimensional fracture mechanics problems: A nonintrusive approach using a generalized finite element method" (2012 (structural) and local (crack) scale problems. In the approach presented here, an initial global scale problem is solved by a commercial finite element analysis software, local problems containing 3-D fractures are solved by an hp-adaptive GFEM software and an enriched global scale problem is solved by a combination of the FEM and GFEM softwares. The interactions between the solvers are limited to the exchange of load and solution vectors and does not require the introduction of user subroutines to existing FEM software. As a results, the user can benefit from built-in features of available commercial grade FEM software while adding the benefits of the GFEM for this class of problems. Several threedimensional fracture mechanics problems aimed at investigating the applicability and accuracy of the proposed two-solver methodology are presented.

“…This characteristic makes this method able to model moving cracks with no update of the mesh during crack propagation. New developments in analysis of crack growth modelling are carried out since XFEM came up [1], for instance the implementation of XFEM in 3D [22], the implementation of XFEM in ABAQU S T M [12], the delamination of GLARE [8], etc. For interested readers, a detail understanding of XFEM is presented in the work of Mohammadi [21].…”

This is the first time this problem is accomplished for computing the stress intensity factors (SIFs) produced in the biaxially loaded area of the cruciform specimen. A static crack analysis for the calculation of the mixed-mode SIFs is carried out. SIFs are calculated for infinite plates under biaxial loading as well as for the CGRP cruciform specimens in order to review the possible edge effects. A ratio relating the side of the central zone of the cruciform and the crack length is proposed. Additionally, the initiation and evolution of a three-dimensional crack are successfully simulated. Specific challenges such as the 3D crack initiation, based on a principal stress criterion, and its front propagation, in perpendicular to the principal stress direction, are conveniently addressed. No initial crack location is pre-defined and an unique crack is developed. Finally, computational outputs are compared with theoretical and experimental results validating the analysis.
