a new nanoindentation approach for independently determining of relaxation modulus and creep compliance of viscoelastic solids

nanoindentation provides an effective technique to measure local mechanical properties at the micro and nano scale nanoindentation also called depth sensing indentation determines the contact parameters from indenter load and depth which measured continuously during loading and unloading processes with the increasing use of very small structures functionally graded materials nanocomposites and other heterogeneous materials in various engineering areas such as electronic mechanical and biological engineering an exact evaluation of deformation and stress in needed to predict reliability and failure behavior of such structures.
