Sintering stability of biporous materials under kinematic constraints

Sintering stability of biporous materials under kinematic constraints

The behavior of porous materials with bimodal pore distribution under external loads and kinematic constraints is considered. Numerical methods of continuum mechanics of sintering are used. The effect of partial and complete constraining of the surface bounding the billets in sintering is studied. C...

Beschreibung
Zusammenfassung:The behavior of porous materials with bimodal pore distribution under external loads and kinematic constraints is considered. Numerical methods of continuum mechanics of sintering are used. The effect of partial and complete constraining of the surface bounding the billets in sintering is studied. Corresponding distributions of small and large pores are determined. The sensitivity of the distributions to constraining/loading paths is established.
