Title: Comparison of the Сontinuous Сonstrained Double Вending process with Еqual Channel Angular Extrusion Conform process by simulation modelling
Keywords: Severe Plastic Deformation, Constrained Continuous Double Be
Abstract: This paper investigates the possibility of creating conditions for severe plastic deformation by continuous constrained double bending (CCDB Conform) with a small relative bending radiuses Rb⁄T of 0.7 to 0.1 in trapezoidal calibers, developed using virtual tools in the CAD/CAE software environment. The CCDB Conform process was analyzed and compared with the ECAE Conform process using the accumulated effective strains, the workability parameter by SPD, the distribution of mean stresses and strain rates determined by simulation modelling. It is found that the equal channel angular extrusion is a special case of the constrained double bending process with a very small relative bending radius (Rb⁄T ≤ 0.1).
