Currently, taking advantage of this technique to investigate the invalid and fracture damage of the materials became a hotspot gradually.
The step pressure value depends on the impact velocity and on the nature of the flyer and target materials, while the step duration is proportional to the flyer thickness.
Both of their materials are aluminum .Their number of SPH particle is 1000 and 20000, respectively, and the original smooth length of that is 10.
In the particular case, where the shock impedances of the flyer and target materials match, the analysis predicts that particle velocity step at the interface should be half the impact velocity.

To meet these requirements, complex-perovskite-type dielectric materials, for example Ba(Mg1/3Nb2/3)O3 and Ba(Zn1/3Ta2/3)O3, have been investigated.
EXPERIMENTAL High purity powders(> 99.9%) were used as starting materials.
Similar to other researchers, it was confirmed that a deviation from stoichiometric composition of complex-perovskite-type dielectric materials shows significant affects on the Q-value.
At first, this concept was applied to the development of BaO-MgO-NbO5/2 system dielectric materials.
