Abstract
Stress fields on elastic-creep bi-material interfaces with different creep material thickness are analyzed by finite element method (FEM). The results reveal that the thicker creep material gives the higher stress intensity near the interface edge at the same transition period and the distribution of the stress intensity does not change further when the thickness-width ratio (h/W) of creep material is larger than 1.0. In addition, the variation of the creep material thickness contributes the effect on the transition period, in which the thicker creep material, the longer time need to reach the steady state.
