Abstract:
This paper describes a modelling approach for the simulation of hypervelocity
impact on fuel tanks using the Smoothed Particle Hydrodynamics (SPH) method. To
determine a suitable particle density, three two-dimensional axi-symmetric
models were analysed. Then three-dimensional simulations with cylindrical and
cubic penetrators were performed. For each analysis the transient pressure
values at locations corresponding to experimental transducer locations were
recorded. The pressure time histories are shown for the axi-symmetric and 3D
models. The simulation results are compared with the experimental results. The
purpose of the research was to demonstrate the capability and potential of SPH
for simulating this type of problem.
