Rheological Model of Sintering and Viscous Flow of Porous Materials with 2D Defects.

The viscous flow and sintering of porous materials that contain 2D defects are analyzed. The analysis relies on the rheological theory of sintering developed by Valerii Skorokhod and on the extended continuum powder model. The behavior of porous materials is considered for the sintering process combined with uniaxial tension. In particular, neutral sintering is addressed and an indirect method to determine the effective Laplace pressure is discussed. [ABSTRACT FROM AUTHOR]
