The Aerodynamic Analysis of Single and Multiple Vehicles Entering and Traveling in Open Tunnels

The analyses required to calculate the aerodynamic effects of tunnel entry, tunnel venting, and multiple vehicle motions in open ended tunnels are presented. Results for several cases of open ended tunnel travel and various entry configurations are presented and described. The effects of an earlier...

Fracture Resistance of Railroad Wheels

The effects of manufacturing method, chemical composition, heat treatment, temperature, and loading rate on the plane strain fracture toughness KIC of railroad wheels have been determined. Carbon content of the wheels is shown to be the principal factor which controls their toughness. One...
