Parameter identification of 42CrMo4 steel hot forging plastic flow behaviour using industrial upsetting presses and finite element simulations [PDF]
An experimental-numerical methodology was proposed for the parameter identification of constitutive laws, when applied to hot forging. Industrial presses were directly used to generate the reference experiments for identification.

Forging process control: Influence of key parameters variation on product specifications deviations [PDF]
Process control in forging industry is essential to ensure a better quality of the product with a lower cost at the end of the manufacturing process. To control the process, a number of key parameters must be monitored to prevent product or forging plan ...

A new route for semi-solid steel forging [PDF]
Forging in semi-solid state significantly extends the possibilities of classical hot forging. In order to fully exploit its potential, the process requires a specific and demanding environment, penalizing its industrial deployment.

Towards the Real-Time Piloting of a Forging Process: Development of a Surrogate Model for a Multiple Blow Operation [PDF]
Forging processes are defined by variables related to the workpiece, the tools, the machine, and the process itself, and these variables are called process variables.

Influence of the constitutive flow law in FEM simulation of the Radial forging process [PDF]
Radial forging is a widely used forming process for manufacturing hollow products in transport industry. As the deformation of the workpiece, during the process, is a consequence of a large number of high-speed strokes, the Johnson-Cook constitutive law (
