Abstract

The large-strain indentation test has been examined using experimental testing and finite element simulation on various engineering polymers. Cylindrical, flat-ended tips with diameter range from 10μm-100μm are used. In the large-strain region, the indentation stress-displacement curve shows linear response from which the mean indentation stress is extrapolated. The mechanism of large-strain indentation has been investigated through optical microscope and finite element simulations. Once a critical indentation depth is reached, the plastic zone surrounding the indenter remains constant.
