Quasistatic tests show device forces vary with standard deviation, σ<6.2% of design and average force. Peak input velocities of ∼200mm/s produced peak resistive forces of ∼350kN and increasingly weak velocity dependence as device input velocity increased,whichisanadvantageasitlimitslargedemandforcestoconnectingelementsandsurroundingstructureiflargerthan expected response velocities occur.
