Mathematic metal forming simulation

Developing a metal pressure treatment technology, you have to know how to calculate the required forces, metal flow nature, stresses and deformations both in the forged part and in the dies correctly. The problem being non-linear, there is no way to find apparently easy analytical solutions. An intricate mathematic procedure is required, instead. The basis for the QFORM finite element software computation core is the metal pressure treatment process simulation using the flow theory. Prof. G.Ya. Gun and his associates have been developing this metal forming simulation approach at the Moscow Steel & Alloys Institute since the seventies. These works were developed further, when designing the computer simulation software for such processes as rolling, extrusion, and forging.
