The modelling of crack propagation was performed using the numerical xFEM method for separating material fibres irrespective of the finite element mesh. Then an example is solved with the subject of the separation analysis of two aluminum beams between which glue is placed, and tips on the use of the cohesive element in Abaqus are taught. The object of study was created from numerical analysis of material failure due to fibre separation using Abaqus 6.14. Numerical simulations of two-dimensional and three-dimensional models were performed in Abaqus 6.14 software using an. UFG Al 6061 alloy processed by cryorolling (CR) and accumulative roll bonding (ARB) was investigated in this work. At the beginning the basics and formulation of the Cohesive Element are presented. In the present work, the tensile and fracture behavior of ultra-fine grained (UFG) Al 6061 alloy was simulated using extended finite element method (XFEM).

Finally, the accuracy, convergence speed, run-time and mesh dependency of each method are discussed. In this tutorial you will learn how to use the Cohesive Element with an example. Finite element results are compared with experimental results available in the literature for unidirectional DCB specimens.

To this end, a composite double cantilever beam (DCB) specimen as a benchmark example is modeled in ABAQUS and delamination propagation is simulated using three above methods and the combination of XFEM with VCCT and CZM. Secondly, the extended finite element method (XFEM) in the ABAQUS CAE was used to. The ABAQUS 6.14 software may offers two different ways to evaluate the full contour. It is often questioned by new researchers and engineers: which method is more appropriate for modeling of delamination propagation in composites? In this study, advantages, limitations, and challenges of each method are discussed with the goal of finding a suitable and cost-effective solution for modeling of delamination propagation in laminated composites. Virtual crack closure technique (VCCT), cohesive zone modeling (CZM) and extended finite element method (XFEM) are three well-known numerical methods frequently used for crack propagation modeling.
