Abstract (EN): In this work, a computational model based on a meshless method, the EFG method, was developed to simulate forging processes. The application of meshless methods in this type of forming processes opened new questions related to crucial aspects associated with the modelling of frictional effects along the contact interface between the tools and the workpiece. In this work to deal with this problem of contact and friction special interface finite elements are established between the tools and the workpiece, blending the finite element and the meshless method in a coupled formulation. One example of application in forging is analyzed together with a numerical implementation by the finite element method for comparative purposes. The obtained results are also compared with the experimental values and others published in the literature.
