Summary The research will compliment through collaboration with the ONR MURI team on Force Protection. Provide high fidelity measurements of the dynamic parameters required for calibration and development of a numerical code that can be used for simulating the response of panels to soil blasts. Initial experiments will determine both the shape and velocity of the soil front and the ejecta thickness. This research will comprehensively characterize the blast wave and, thereby, calibrate and validate the dispersion aspects the Deshpande et al constitutive law used for the soil. The pendulum will not be used; instead, the high-speed camera will record soil wave profiles as they exit the blast chamber. Characterization of the blast wave will also serve to fine-tune the details of detonation, such as camera trigger timing and detonator placement. second set of experiments comprises soil blast impacts upon metal and composite plates mounted onto the pendulum, These will utilize the full instrumentation package. Peak loads and transferred momenta will be recorded by the Kolsky bars and pendulum displacement, respectively. In addition, the dynamic deformation of the back faces will be recorded with the high-speed camera using the shadow Moire technique. The responses of these panels to soil impact will be used to fully-calibrate and validate the Deshpande et al dynamic soil compaction model. They will also be used to explore momentum transfer incorporating Fluid-Structure-Interaction (FSI).
