摘要：

A method for calculating viscoelastic stresses that develop around heterogeneities during sintering uses constitutive laws derived from experimental data obtained on porous partially sintered bodies. Analysis of stresses using literature data for Al//2O//3 reveal that the stresses around heterogeneities vary with density, particle size and temperature. The largest stresses occur in association with hard agglomerates.
