The compaction process involves stress transmission via rigid or flexible (die) walls and the
propagation of stresses within a powder mass. The particles that comprise the powder …

In this paper, the Coulomb friction law and the constant shear friction law were compared
and investigated in detail using a rigid-plastic finite element method with emphasis on their …

The discrete element method (DEM), based on a soft-sphere approach, is commonly used to
simulate powder compaction. With these simulations a new macroscopic constitutive relation …

A discrete and continuum modelling approach to powder compaction is presented and
discussed. The work demonstrates the ability of the discrete method to capture the …

In this paper, a general framework for the finite element simulation of powder forming
processes is presented. A large displacement formulation, based on a total and updated …

In this paper, a double-surface plasticity model, based on a combination of a convex yield
surface consisting of a failure envelope, such as a Mohr–Coulomb yield surface and, a …

An efficient combined finite/discrete element procedure is developed, which is intended for
simulating compression of 3D particle assemblies. Its main ingredients are an explicit …

In this paper, a transient dynamic analysis of the powder compaction process is simulated by
a large displacement finite element method based on a total and updated Lagrangian …

In this paper, the transient dynamic analysis of metal powder during the cold compaction
process is simulated by the finite element method based on a 'Total'and …

The die pressing test is widely used to investigate the mechanical behaviour of powders.
However, analysis of the results may be problematic because of the effects of powder-wall …
