Simulation technique models material-aging process

The nation’s aging infrastructure requires massive investment. The American Society of Civil Engineers estimates the U.S. needs to spend some $4.5 trillion by 2025 to fix the country’s roads, bridges, dams and other infrastructure.

Imagine if engineers could build structures with materials that do not degrade over time. Researchers at the University of California, Irvine have proposed a new simulation technique that could help engineers do just that.

Mohammad Javad Abdolhosseini Qomi, assistant professor of civil and environmental engineering, and engineering graduate student Ali Morshedifard have developed a numerical method to simulate the molecular aging process in amorphous materials, such as concrete and glass.
