The energy required to puncture a material by impact with a falling dart under specified test conditions. This test measures the multiaxial impact behavior of a material and can be used as a measure of the rate sensitivity of a material.
Impactor Head
A 12.7 mm (0.5 in) diameter hemispherical head dart is dropped from a height sufficient to produce a specified impact velocity. The dart is equipped with load and displacement transducers so that a load/displacement plot of the test can be produced. Energy is the area beneath the load/displacement plot. Energy reported is either energy to peak load or total energy.
