Modeling of Forging and Other Bulk-forming Processes

By Rebecca Gurk on Wednesday, December 14th, 2016 in Additive Manufacturing, Advanced Manufacturing, Aerospace, Automotive, First Time Quality, Forming, Heavy Industry, Heavy Manufacturing, Manufacturing Innovation, Mechanical Design, Modeling & Simulation. No Comments

Many manufacturers use bulk metal forming processes such as forging and extrustion to produce complex metal components. Finite element analysis (FEA) can be used to model bulk metal-forming processes. These simulations provide information that is difficult or impossible to obtain from experimental trials, and can determine whether part defects such as unfill and laps willRead more
