“…Considering the complex nature of most delamination problems, the finite element method (FEM) is found to be the most suitable tool for simulation. The Virtual Crack Closure Technique (VCCT) has been utilised in the investigation of delamination in many published studies ( (Jokinen, Wallin & Saarela 2015;Shokrieh et al 2012). VCCT analysis relies upon two basic hypotheses; namely, that the energy released during crack growth is identical to the energy required to close the crack and the stress state does not change significantly when the crack is extended (Bonhomme et al 2009).…”

“…Hence, modeling crack growth within the FE method requires the use of extrinsic criteria and modeling approaches. The virtual crack closure technique (VCCT) [2][3][4][5][6] and cohesive zone model (CZM) [7][8][9][10][11] are the most commonly accepted approaches for predicting delamination onset and growth.…”

“…VCCT was first introduced by Rybicki and Kanninen 7 and have been used by researchers since then to identify the interlaminar fracture characteristics of composite materials. [6][7][8][9][10][11] Davidson et al 12 modeled double cantilever beam (DCB) and end-notched flexure specimens (ENF) with three-dimensional (3D) shell elements to investigate the influence of bending-bending and the bending-twisting couplings of multidirectional laminates on the strain energy release rate (SERR) distribution along the delamination tip using VCCT. Similar investigations are performed for mode II interlaminar fracture and mode I interlaminar fracture by other researchers using 3D 8-node solid elements to identify the influence of the elastic coupling-related instabilities on the crack propagation.…”

The virtual crack closure technique is a well-known finite element–based numerical method used to simulate fractures and it suits well to both of two-dimensional and three-dimensional interlaminar fracture analysis. In particular, strain energy release rate during a three-dimensional interlaminar fracture of laminated composite materials can successfully be computed using the virtual crack closure technique. However, the element size of a numerical model is an important concern for the success of the computation. The virtual crack closure technique analysis with a finer mesh converges the numerical results to experimental ones although such a model may need excessive modeling and computing times. Since, the finer element size through a crack path causes oscillation of the stresses at the free ends of the model, the plies in the delaminated zone may overlap. To eliminate this problem, the element size for the virtual crack closure technique should be adjusted to ascertain converged yet not oscillating results with an admissible processing time. In this study, mesh size sensitivity of the virtual crack closure technique is widely investigated for mode I and mode II interlaminar fracture analyses of laminated composite material models by considering experimental force and displacement responses of the specimens. Optimum sizes of the finite elements are determined in terms of the force, the displacement, and the strain energy release rate distribution along the width of the model.
