New Iranian Model for Nanocomposite Materials Saves Time, Money

Tehran, Iran | Posted on August 8th, 2009

According to the Iranian Nanotechnology Initiative Council, "Compared to ordinary materials, nanomaterials exhibit special and different magnitudes of mechanical properties such as hardness, endurance and dissipation. These properties can be measured whether by experiments or using an appropriate predictive model," Saeed Ziayirad, professor of mechanical engineering department at Isfahan University of Technology said.

"A proper mechanical behavior model is able to calculate these properties by numerical methods. This practice not only cuts different production costs but also lets the researchers prepare their proper compound faster," Ziayirad reiterated.

Given the significant characteristic of nanocomposites which is their energy dissipation behavior especially pronounced under periodic loading, Ziayirad and his colleagues proposed a model which predicts dissipation of metallic nanocomposites under loading conditions.

They prepared metallic nanocomposites by mechanical alloying method and performed experimental analysis. By comparing model predicted dissipation behavior of samples with the one obtained by experiments, they observed good agreements and were able to enhance their primary model.
