【 摘 要 】

This thesis focuses on shaped charge simulations using a hydro-code called ALE3D.It gives background on shaped charge research and motivation for the project itselfalong with information on a shaped charge experiment that took place at the Universityof Illinois Urbana Champaign. A baseline simulation is created to mock the experimentand compare results. Next, a series of simulations are conducted varying parameterssuch as HE, liner, and target material and analyzing output data. Then a secondproposed shaped charge experiment with different geometry and materials is simulated.Finally a newer topic of asymmetrical defective shaped charges is explored by means ofsimulations. It also advances on shock states for a hyper-elastic solid using the Blatz-Koequilibrium relations and general conservation laws. Basic Rankine-Hugoniot relationsfor longitudinal isotropic motion are determined. To further this topic, a study ofanisotropic materials was conducted using ALE3D.
