On the Fragmentation of Explosively-driven Plastic/steel Layered Cylinders
Autor: Adrian Rotariu, Florina Bucur, Eugen Trana
Publikováno v: Materiale Plastice. 55:521-523
While over the past century fairly extensive work has been carried out on explosively-driven metallic envelope fragmentation, as the development of explosive materials and warhead configurations continued, the issue under consideration is still topic
