The relation between the free-volume and the cook-off response
conference paper
At TNO Prins Maurits Laboratory (TNO-PML), a considerable effort has been put into the research of energetic materials and their responses to several types ofstimuli. In the lastfew years, a part ofthis research has been focused on the response to a thermal stimulus cook-off. The TNO-PML Cook-off test, is now capable of measuring lhe temperature distribution, the strain and pressure, during the cook-off process. At the same time, new strain measurement techniques are under development. During one of the test series with Composition B, an unexpectedly mild explosion was found in the cook-off test. To investigate this more thoroughly, a series of experiments with Composition B was performed. Because no detonation reaction was found, a new series of tests with Composition B was planned. Especially the influence of the free volume on the response has been studied.
The results ofthese investigations are presented, showing a correlation between the response in cook-off and the free-volume in the cook-offtest tube.
