Abstract
The creep indentation testing with cylindrical flat indenters has been simulated by the
finite element method with special attention on the creep damage of the indented
materials. For the equivalent-stress-controlled-damage materials, the user subroutine
Creep has been programmed for Abaqus, which is used to analyze the one-phase
half--infinite material and thin-film/substrate material systems. It is found that the
creep indentation depth rate is influenced by the damage parameters of the indented
materials as well as the size of the indenters and the ratio of the
indenter size to thickness of the thin film.
It is a possible, like that of the non--damage
creep indentation experiments, to obtain the creep damage
law of the indented materials
from the creep damage indentation
testing.
