Powder Compaction of a Cup

Application ID: 46931


The fabrication of a cup through powder compaction is simulated in this tutorial model. The powder compaction process is becoming common in the manufacturing industry, due to its potential for producing components of complex shape and high strength.

Combining the Fleck-Kuhn-McMeeking (FKM) model with the Gurson-Tvergaard-Needleman (GTN) model for porous plasticity makes it possible to cover a wide range of porosity values. This example uses that technique and takes into account the friction between metal powder and die.

The highly nonlinear structural analysis is performed by considering the contact interaction between the moving parts, the elastoplastic constitutive law selected for the metal powder, and the geometrical nonlinearity caused by the large displacements.

This model example illustrates applications of this type that would nominally be built using the following products:
