Abstract
Asymmetric creep behaviors of ceramics under high temperature were investigated. Based on the Norton's power-low creep equation, multidirectional creep equations were proposed for general geometric loading conditions. The proposed equations were implemented into finite element program (ABAQUS) to simulate creep behaviors of ceramics in complicated loading conditions. The calculated results were compared with experimental data for uniaxial compression of Si-SiC C-ring and flexure of Si-SiC and
