A constitutive formulation for viscoplastic porous materials subjected to finite deformations is developed. To account for porosity effects on the viscous response it is proposed an apparent viscosity, that is, it is assumed that the viscosity depend

In this work, we develop a strategy to derive the tangent modulus A that takes into account the corrections imposed by the evolution of the relative density in the analysis of density-dependent materials, compressible materials. Special attention is

In this work the simulation of the powder compaction process, in the context of Powder Metallurgy, is numerically investigated. The procedure considers that the powder is being modeled by a complete smooth three surface Cap model and makes use of a s
