Material with Improved Absorption of Collision Forces for Railroad Cars

The purpose of this project is to develop and perform an extensive experimental and numerical investigation and evaluate the dynamic properties of composite metal foams (CMF) at various impact speeds. This will include different speeds mimicking those of railroad car collisions, at different speeds, including high speeds. This investigation will provide the fundamental understanding of the behavior of CMF that is of critical importance before composite metal foams can be implemented effectively to increase protection against hazards and damage in potential railroad car collisions. The outcome of this work could lead to safer and more efficient railroad car safety structures along with less weight. The reduced weight of these components could also help to lower costs for production and operation and improve fuel economy.
