✦ Synopsis

In this study the theory of viscoplasticity is employed to provide a unified approach to the problems of plasticity and creep. For plastic compressible materials, the viscoplasticity equation is formulated and the effective range of the equation is discussed. The Drucker-Prager potential is used to describe the plastic compressible yielding and the strength-differential effect. The influence of the strength-differential effect is investigated for a pressurized cylinder.

Finite element method (FEM) simulations of pharmaceutical tablet compaction using a Drucker-Prager Cap (DPC) model are presented in which material properties are relative density (solid fraction) dependent. Results from the solid fraction dependent model are compared to those from a constant propert
