A dual-mesh approach to ring-rolling simulations with emphasis on remeshing
چکیده انگلیسی

In this paper, we present a ring-rolling simulation technique, with emphasis on remeshing capabilities. The technique is based on a dual-mesh approach, in which a finite element analysis model is divided into fine sectors and coarse sectors, and three different kinds of remeshing are used. The first of these, which is obligatory, replaces a coarse sector with a fine sector when the coarse sector approaches a plastic deformation zone. The second and third kinds, which are introduced in this study, respectively involve changing the number of sectors and changing the grid system of the frames used to construct the sectors. These remeshing schemes are discussed in detail, and several applications are utilized to demonstrate their characteristics and capabilities in the dual-mesh approach to ring-rolling simulations.
