| Abstract: | A three-dimensional finite, element model for the simulation of isothermal hot forging is presented. The material behaviour is assumed to be incompressible visco-plastic (Norton–Hoff law), with the associated friction law. The velocity field is calculated with a finite element approximation using eight node hexahedral or six node prismatic elements. An explicit Euler scheme is used for time integration. Simulations of compression of a cubic block and horizontal cylinder are performed. The computed results are compared with experimental measurements made on special Plasticine. |
