Abstract:
A mesomechanical simulation of porous aluminum shock loading is performed by means of a modified 2D SPH method applied to thermo-elastic-plastic medium. The periodic structure of porous material is presented explicitly and the properties of solid aluminum are used. The shock loading is simulated by the impact of a porous plate against a rigid wall. The material flow fields show major features of loading dynamics: multiwave shock structure at low shock intensities, hydrodynamics of the pore collapse in a strong shock and formation of the two-step material compression at the shock front, the generation of pressure oscillations behind the shock front and the influence of heat conduction on the oscillation attenuation. The computed Hugoniot is well fitted with the experimental data.
