... process. The modified cam-clay model was used to describe the constitutive equation of porous stainless-steel SLS components. The densification process of SLS porous components was simulated using the finite element method. The visual distributions of shape change, displacement, density, and stress were...

... of the densification of HA. The bulk density (or porosity) governs the mechanical properties when the porosity is high. When the bulk density (98.2% at 900 ° C and 44.6 MPa ) was close to the theoretical density, in the present study, no significant increase was observed when the temperature...

To simulate densification and deformation of a powder compact in a container during hot isostatic pressing...

...) to simulate densification of ceramic powder under cold compaction and pressureless sintering. Finite element calculations were compared with experimental data for density distribution and deformation of zirconia powder compacts under cold combination pressing and pressureless sintering. Finite element results...

... ). At this low stress ratio there is an intense shear deformation and limited densification before the deformation becomes localized and the specimen fails. Contours of constant work per unit current volume are presented in Fig. 3 . When presenting the results in terms of work, the initial stages...
