Abstract
THE OBJECTIVE OF THE PROPOSED WORK IS TO ANALYZE THE HYPERVELOCITY MODELS TESTED AT ARNOLD ENGINEERING DEVELOPMENT CENTER TO DETERMINE THE CAUSE OF NOSETIP FRACTURES. WE WILL ACCOMPLISH THIS GOAL BY PERFORMING TWOAND THREE-DIMENSIONAL FINITE ELEMENT ANALYSES OF THE HYPERVELOCITY MODEL USING DYNA2D AND DYNA3D. IF NECESSARY, WE WILL ALSO DO HYDRODYNAMIC ANALYSES OF THE GAS EXPANSION WHICH DRIVES THE PROJECTILE (HYPERVELOCITY MODEL). AS A RESULT OF THE ANALYSES, WE WILL RECOMMEND CHANGES THAT CAN BE MADE TO REDUCE THE PROBABILITY OF FAILURE OF THE MODELS.
