Creep properties from indentation tests by analytical and numerical techniques
-
Matteo Galli
Abstract
Analytical and numerical methods for the identification of creep properties of two polymers and indium from indentation tests are compared. Creep indentation experiments are performed at fixed peak force following ramp loading. The experiments are modeled both by analytical techniques and by finite elements and the models are integrated in an identification routine. The assumed mechanical behavior allows for a satisfactory fit of the experimental data. For the considered viscoelastic materials analytical and numerical modeling are equivalent whereas for indium finite element modeling is to be preferred since the analytical model is not representative at the large levels of plastic strain experimentally obtained.
