Finite element analysis of forging.

摘要

Numerical modeling and simulation of metal forming is very effective in saving production time, effort and economy and has thus gained prominence in many industries all over the world. In metal-forming finite element analysis, software like Deform, Qform, Forge, Simufact, Hyperform are used extensively for the forming analysis. Apart from having narrow applications, these software are expensive. The object of this study was to examine the robustness of general package software in regards to forging. Software such as Abaqus and Ansys LSDyna were used to simulate the forging process. The case examined was that of a circular metal disc restrained at the outer boundary and deformed from the center.
