Multiscale Modelling of Nanoindentation [PDF]

Key Engineering Materials, 2007
Nanoindentation is an interesting technique used to probe the local mechanical properties of a material. Although this test has been widely used and developed over the world during the past few years, it remains a lot of uncertainties regarding the interpretation of nanoindentation data. In this study, we propose to simulate the nanoindentation test of

The Nonlinear Visco‐Hyperelastic Damage Mechanics of Individual Electrospun Polycaprolactone Fibers: Experiments and Modeling

Advanced Engineering Materials, Volume 27, Issue 13, July 2025.
This study investigates the complex mechanics of individual electrospun polycaprolactone fibers under small and large strains. Combining experiments with a visco‐hyperelastic damage model, this work reveals and quantifies these fibers’ nonlinear behavior, including strain‐stiffening, viscoelasticity, and damage.

Nanoindentation of Multifunctional Smart Composites

Polymers, 2022
Three multifunctional smart composites for next-generation applications have been studied differently through versatile nanoindentation investigation techniques. They are used in order to determine peculiarities and specific properties for the different composites and to study the charge/matrix, charge/surface, or smart functions interactions. At first,
