- Nanoindentation is routinely used to derive localised values of mechanical properties including Young’s modulus. Operators use standard formulae to calculate modulus. The theory behind the formulae assumes isotropic material with identical response in tension and compression. Oriented polymers possess neither of these properties. The paper presents a numerical analysis validated for highly oriented polypropylene. It has been cited in high-profile journals and was presented at the Polymer Processing Society Annual Conference in Taipei, 2018. One of the authors has taken up an appointment with Hitachi High-Tek, AFM and nanoindenter manufacturer.
