Collisions and following shock compressions of matter are frequent events in the Solar System. Many of natural solids are porous and their behavior under compression differs of non-porous solids. Here we want to investigate energy partitioning for several porous and non-porous materials.
Autodyn is used to consider energy partitioning for water, sand, rhodium and iron during hyper velocity impacts. The impact velocity ranges from 0.6 km/s to 80 km/s and pressure may change from 1 GPa to 3000 GPa.
The calculations also assume that the materials are porous ones with the distention (m=V00/V0) changing from 1.0 to 2.5 and use the P-alpha model for the description of porous materials.
We are also going to perform a low velocity (0.7 km/s) impact experiment at the Seismological laboratory of Caltech and compare the results with the result of the calculations.
