Abstract

The initial collapse load and the energy absorbed during collapse were measured for brass tubing over a range of compression rates from ∼ 2 × 10−4 m/s to ∼ 12 m/s using two different load cells. Large differences in the initial collapse load under quasi-static loading could be produced by different trigger mechanisms. These differences were reduced as the compression rate was increased. Load cell inertia effects could cause the true form of the load/compression curve to be obscured. Although such ringing responses precluded accurate measurements of the initial collapse load, the measured energy absorbed during the collapse was not affected.
