Effect of unloading strain rate on the elastic modulus of a viscoelastic solid determined by nanoindentation

Fujisawa, Naoki; Swain, Michael V.


The elastic modulus of an amorphous polymer was investigated by nanoindentation using combinations of ten total penetration depths and three constant unload rates. This experimental design provided a range of unloading strain rates coexisting with a range of depths. The elastic modulus of the material was found to correlate strongly with the unloading strain rate, whereas its correlation with the indentation depth was statistically nonsignificant. Thus, the increase of elastic modulus that...[Show more]
