Penetration mechanics modeling of composite armor is one of our major expertise. Depth of Penetration (DoP) experiments (at NTS Chesapeake Testing) and LS-Dyna computational modeling have been carried out by Dr. Haque in developing proprietary penetration equations for composites.
Finite element modeling and simulations of full 3D compression and tension Split Hopkinson Pressure Bars (manufactured by REL Inc) experiments with 3D metal and composite specimens allows the computational determination of material model parameters e.g., Johnson & Cook, composite damage model MAT162 in LS-DYNA.
Book published by Dr. Haque: Split Hopkinson Pressure Bar Technique: Experiments, Analyses, and Applications.
Impact and damage modeling of composites using state-of-the-art rate dependent progressive composite damage model MAT162 in LS-DYNA are provided for different impact applications, e.g., automobile, aircraft, spacecraft, space-suit, and space-habitat applications.
Design of ballistic impact experiments, ballistic testing services (at NTS Chesapeake Testing), post-ballistic damage evaluation, determination of ballistic limit velocities (using Haque & Gillespie ballistic equations) or V50's, determination of depth of penetration parameters, detail analysis of results are provided.
