Three Dimensional Modeling of Steady-State Metal Forming Processes

点击翻译按钮获取中文摘要

Three-dimensional modeling of industrial metal forming processes using an Eulerian reference frame will be performed. Common processes such as rolling, drawing, and extrusion will be evaluated. These processes all involve a high degree of mechanical-thermal-material coupling. A model which accounts for this coupling and an algorithm for handling this coupling is being developed. A finite deformation theory for the elastic-plastic kinematics must be used to handle the large deformations being considered. The planning stage of this project, the model, algorithm, and code development will be handled in collaboration with colleagues at Rensselaer and Alcoa Laboratories.
