Temperature and Strain Gauge Measurements in the TNO-PML Cook-off Test.
Abstract
After a literature research, the development of the TNO-PML Cook-off test started in 1987. During the years of development, many modifications were made to the test object. In this configuration, test data can be obtained to verify the thermal/chemical Cook-off computer models. Because the general interest is more focused on the level of severity in a Cook-off event, the development of the TNO-PML Cook-off test went in the same direction. Detonation and deflagration to detonation transition (DDT) experiments have been carried out to measure the strain/strain rate during the last phase of the explosion. The results show a trend in the increasing rate of strain of the different phases of the DDT experiment. First results of the Cook-off experiments look very promising, although a quantitative analyses is not yet possible. The radial temperature distribution curves in the center of the Cook-off experiments reveal interesting information about endothermic and exothermic reaction steps, and melting and crystal phase transitions of the explosive substances. Future investigations will be more focused on the improvement of the strain gauge technique to quantify the level of severity of a Cook-off reaction.
