Development of the modeling system core for severe plastic deformation processes

Abstract The research is focused on the development of the structure of the core of the integrated automated modeling system (AMS). The AMS ensures an increase in the functionality of the CAD and CAE systems by combining them with several external independent modules. The AMS modeling technological schemes of severe plastic deformation processes, the behavior of materials in deformation processes, and reducing the cost of choosing the scheme and parameters of the deformation processes. Object-oriented software was developed to analyze the influence of different initial shapes of the billets and the die sets on the changes in the billet’s cross-section during deformation. The software is written in C# using the WPF interface and the page structure of the main application window. Using parametric models of processes enables automated calculations in CAE systems and the generation of 3D geometric models of die sets in CAD systems. The design of experiments allows automation research of severe plastic deformation (SPD) processes and reduces the costs of studies. Importing and accumulating calculation results in the CAE system made it possible to find the optimal values of the parameters of SPD technological processes. The parameters of the deformation models obtained based on modeling are the basis for constructing the geometry of the die set in CAD with subsequent integration with CAE to calculate the stress-strain state in the volume of the billet. Ways to expand software functions to support various SPD processes are proposed.
