Low amplitude insult project: Structural analysis and prediction of low order reaction
The low velocity impact sensitivity of PBX 9501 has been investigated through a series of experiments based on the Steven Test targets and a set of Shear Impact experiments. The authors describe calculations done using DYNA2D, SPRONTO and DYNA3D to support these, and other, low amplitude insult experiments. The calculations allow them to study pressure and strain rate variables, to investigate structural aspects of the experiment, and to predict velocities required for reaction. Structural analyses have played an active role in this project beginning with the original target design and continuing through analyses of the experimental results. Alternative designs and various ideas for active instrumentation were examined as part of the experiment evolution process. Predictions of reaction are used to guide these design studies, even though the authors do not yet have enough experimental data to fully calibrate any of the models.
