DISPLACEMENT RESISTANCE DEVICE FOR A VEHICLE CRUSH-CAN ASSEMBLY AND CRUSH-CAN YIELD ADJUSTMENT METHOD

A vehicle system includes, among other things, a crush-can assembly that is disposed between a bumper member and a vehicle frame. The crush-can assembly is configured to yield when the bumper member is moved closer to the vehicle frame. The system further includes a displacement resistance device that has a chamber that holds a liquid-nano material. The liquid-nano material is compressed within the chamber to resist a movement of the bumper member toward the vehicle frame.
