Dynamic mechanical response and damage effects of Ni-Al-W structural energetic material under explosive loading

摘要：

　　Dynamic response behavior of the Ni-Al-W structural energetic material under explosive loading and damage effects on bi-layered space target are carried out.The results show that in the protection of the lower wave impedance material buffer, the Ni-Al-W fragments are capable of withstanding to explosive loading with acquiring initial velocity of 2256m/s.The Ni-Al-W fragments undergo intermetallic reaction and oxidation reaction upon impacting.The Ni-Al-W fragments also have advantage of perforation in area against the bi-layered space plates.The areas of hole in the 1.5mm thick aluminum plates perforated by NI-Al-W fragments of 7.4g is 3 times larger than that of steel fragments of 7.8g with initial velocity 2256m/s and 2205m/s respectively.
