... higher CO 2 emissions as compared to conventional manufacturing methods such as forming and machining. Thus, the demand for sustainable and green manufacturing also compels manufacturers to think more on the improvement of the efficiency of heat treatment. In the last three decades, the computer...

... SM, UBM, and FEM approaches in predicting force and torque in cold flat rolling. They found that each approach had its own region of superior performance. More recently, Hsu and Tzou ( Ref 6 ) compared slab and UBM approaches in modeling double-layer clad sheet compression forming. In this, the metal...

.... Therefore, the updated Lagrangian formulation is appropriate for the simulations of sheet metal forming processes. For theses analyses, the Lagrangian frame of reference is redefined at the last completed iteration of the current increment. The variational form of the equation for the static problem in the...

... dominant effect on the ability of a material to flow plastically, regardless of the other variables. In many forming operations, controlling the mean normal stress σ m is critical for success ( Ref 1 , 2 ). Compressive forces that produce low values of σ m increase the ductility for a variety of...

... technology is characterized by multiple impact blows between contoured dies. Hammers are primarily used for hot forging; for coining; and, to a limited extent, for sheet metal forming of parts manufactured in small quantities—for example, in the aircraft/airframe industry. Hammers are capable of developing...

The output is amplified and transmitted to a pen recorder, which forms an image by burning the surface layers of an ink-impregnated electrically conductive paper. Larger signals produce a darker gray shade on the image. The transducer...
