• Application study •
Finite Element Method (FEM) was used to simulate the creep indentation
testing on film/substrate systems. Based on the FEM simulation, a new method
is proposed to derive the material creep properties (in Norton equation) from
the indention creep experimental results (indentation stress-indenter
depth-time) for thin film/substrate systems by the definition of
`effective' stress and `effective'
strain. In the simulation, a steady state was found and the steady state was used to
construct the relationship between the traditional uniaxial tensile creep testing and
indentation testing. In the simulation of the creep indentation
testing, FEM-results showed that the experimental results would have
some error from ignoring the influence of the substrates even if the
indentation depth did not exceed 5%~10% depth of film.
