Abstract
Indentation experiments with indentation depths in the nano- and micrometer ranges in the literature have shown that that an indentation size effect similar to metals is present in polymers. In this paper we present indentation ex- periments of a polyamide/imide polymer of indentation depths in the range of 1 to 30 microns. An increase in hardness of about 70% was observed at small indentation depths compared to hardness at large indentation depths. The indentation re- sults are discussed with respect to an indentation hardness rule based on Frank elasticity suggested in a previous paper by the authors. It is found that the hardness model agrees well with the experiments.
