Abstract Scope |
Piezospectroscopic (PS) nanocomposites yield the ability to directly measure the amount of stress within the embedded nanoparticles. PS measurements have shown the loading ratio between the particle and composite to be much higher compared to some classical analytical methods. These methods do not include effects of interacting and contacting particles. Here, a particle interaction term is introduced into classical methods to improve the accuracy of nanocomposite mechanics. This will be completed by implementing a term for inter-particle contact into current predictive techniques, and also have this term weighted by the probability of contact occurrence. The implications of this work will bring a better understanding of the inter-particle behavior, load transfer theory, and predictive techniques that are currently characterizing the field of nanocomposites. The analytical method proposed in this work was compared with a similar numerical approach using finite element methods, and the two approaches showed good agreement. |
