Bighorn sheep (Ovis canadensis) is known for its giant spiral horns that can sustain impact loading at a speed up to 5.5 m/s during ramming without causing severe damage or head concussion. The bighorn sheep horn is composed of a keratin-based bio...
Roadside safety hardware systems play a vital role in reducing both the number and severity of multi-vehicular collisions by preventing errant vehicles from traversing through an open median into oncoming traffic. The safety hardware used to preve...
