SHPB(Split Hopkinson Press Bar) can be used as test system to determine dynamic mechanics characteristic of brittle materials.
Most experimental and researchers think that the dynamic stress balance should be satisfied in the system to perform fracture test of brittle materials.

Among the various material, electroactive polymers (EAPs) are of the promising candidate materials which have the capability to convert energy from mechanical energy to electrical energy and vice versa.
Compared to other materials, EAPs have various advantages such as flexibility, large dimensional change, easy processing, light weight, and low coast [3].
