“…Recently, a new numerical method based on VCCT was proposed by Xie et al [37,38], which allows the calculation of strain energy release rates for cracks that kink. This method allows the evaluation of the mode I and mode II energy release rate at the tip of a kinking crack using only the nodal forces and displacements near the crack tip.…”

Recent developments in fracture mechanics analyses of the interfacial crack problem are reviewed. The intent of the review is to renew the awareness of the oscillatory singularity at the crack tip of a bimaterial interface and the problems that occur when calculating mode mixity using numerical methods such as the finite element method in conjunction with the virtual crack closure technique. Established approaches to overcome the nonconvergence issue of the individual mode strain energy release rates are reviewed. In the recent literature many attempts to overcome the nonconvergence issue have been developed. Among the many approaches found only a few methods hold the promise of providing practical solutions. These are the resin interlayer method, the method that chooses the crack tip element size greater than the oscillation zone, the crack tip element method that is based on plate theory and the crack surface displacement extrapolation method. Each of the methods is validated on a very limited set of simple interface crack problems. However, their utility for a wide range of interfacial crack problems is yet to be established.

“…The VCCT is a well established method for the computation of the energy release rate (ERR) based on results from finite element analysis (Rybicki and Kanninen [20], Xie and Waas [22], and Krueger [12] and references therein). The VCCT is computationally efficient and provides the modal contributions to the total ERR, where the latter is crucial for mixed mode fracture analysis.…”

This paper proposes a novel, efficient, and accurate framework for fracture analysis of beam structures with longitudinal cracks. The three-dimensional local stress field is determined using a high-fidelity beam model incorporating a finite element based cross section analysis tool. The Virtual Crack Closure Technique is used for computation of strain energy release rates. The devised framework was employed for analysis of cracks in beams with different cross section geometries. The results show that the accuracy of the proposed method is comparable to that of conventional three-dimensional solid finite element models while using only a fraction of the computation time.
