A Modeling Tool for Contact Probe Tests on Nano-Particle Filled Materials

Abstract:
With the recent advances in nano-scale science and engineering, materials containing reinforcement with superior mechanical properties can be found in many advanced products. The accurate prediction of the mechanical properties of this class of composite materials is important to ensure the reliability of the products. Characterization methods based contact probe such as nano-indentation and scratch tests have been developed in recent years to measure the mechanical properties of the new class of nano materials. This paper presents a constitutive modeling framework for predicting the mechanical properties of nano-particle reinforced composite materials. The formulation directly considers the effects of inter-nano-particle interaction and performs a statistical averaging to the solution of the problem of two-nano-particle interaction. Final constitutive equations are obtained in analytical closed form with no additional material parameters. The predictions from the proposed constitutive model are compared with experimental measurement from nanoindentation tests. This constitutive model for nano-paticle reinforced composites can be used to determine the volume concentration of the reinforcing nano-particles in nano-indentation test.
