Tungsten alloy cylindrical fragment is one of the commonly used prefabricated fragments, and has been increasingly used as a killing element. There are other two types of prefabricated fragments. They are tungsten alloy spherical fragment and tungsten alloy square fragment. Cylindrical fragment made using high-density tungsten alloy as raw materials has excellent molding characteristics, high killing efficiency, strong armor-piercing ability and speed-storage ability, so that it can effectively kill personnel, no armor or light armor targets, such as aircraft, radar, missiles and other weapons and equipment.

According to the literature, the shape factor has a great influence on the attenuation coefficient, and the attenuation coefficient is directly related to whether the tungsten alloy cylindrical fragments can effectively damage the target. In other words, it is very meaningful to study the shape factor of the cylindrical fragment to improve the power design level of the fragmented warhead. Therefore, many researches on cylindrical fragments now focus on the shape factor of fragments.
