Abstract

A methodology has been developed to determine constitutive laws of nanoparticles from in situ nano-compression experiments in a transmission electron microscope. It is based on image analysis to obtain relevant load-displacement curves, followed by finite element analysis associated to an inverse method. A transition alumina, stable only at the nanometer size, has been characterized as an example. The Young modulus and yield strength of this transition alumina, not available for such crystallographic structure, have been obtained.
