Titel
Modelling of anisotropic shrinkage during liquid phase sintering
Abstract
Green bodies made by tape casting, extrusion or uniaxial die compaction may ehib it appreciable sintering anisotropy. To account for this, a micromechanical liquid phase sintering model was extended to take the anisotropic shrinkage into account. Starting point is the liquid phase sintering model of Riedel and co-workers, which includes particle rearrangement, flattening of particle contacts and grain coarsening as densification mechanismus. The anisotropic model is implemented in the finite element code ABAQUS as a material subroutine.
