WARHEAD FRAGMENTATION EXPERIMENTS, SIMULATIONS AND EVALUATIONS
The fragmentation of a detonating 40mm×53 High Explosive warhead was studied to analyze the quality of two test methods. In the first test a detonating warhead were placed within a water container and the fragments were recovered. In the second test (box-test), the warhead was surrounded by steel plates, detonated, and the penetrations and dents were counted to give the total number of fragments. The two tests gave significant deviation in results. An important question was raised. Would the forces when impacting the water cause any damage of the fragments? With computer modelling and microscopy we were able to answer this question. Conclusion: The water container test gave an incorrectly picture of fragment numbers and mass-distribution. The fragment recovery rate was too low. We discovered test induced plastic deformation and abrasion on fragments.
