A new version of the contact-based mechanical model with the strict application of Sneddon’s principles.
The trimechanic theory is the very concept of composite nanomechanics underlying the restoring mechanism
of the material under an external compression. It provides a disentanglement of the linear and tip-shape related mechanical responses at various indentation depths.
The trimechanic theory applies to all contact-based mechanical models with a power-law force–depth relationship. The perspective of this research is that stiffness measurement will not remain at a level of global assessment, but will go further to link elastic behaviors with the substructure of the nanomaterial.
