Abstract

This paper demonstrates a new displacement modulation technique for using a depth sensing nanoindentation instrument to measure the dynamic mechanical properties of viscoelastic materials. For testing low modulus, high damping polymeric materials, dynamic nanoindentation offers several advantages over quasi-static testing. In this research, a model for the dynamic response of the system is proposed and shown to match well with experimental observations. A new calibration procedure, which involves the use of a variable cantilever spring, is employed to determine the damping characteristics of the testing frame as a function of excitation frequency. Using the proposed procedure dynamic nanoindentation tests are carried out on a viscoelastic material to determine the storage and loss moduli as functions of excitation frequency. Finally, a comparison with results from conventional testing (DMA) is provided.
