摘要:The dynamic fracture and fragmentation of notched rings under explosive loading were modeled to investigate the fragment characteristics (average fragment size and fragment size distribution) and their effects on fragmentation performance. An analytical model of the average fragm...

摘要:By analyzing the fragmentation distributions of a cylindrical structure and a specific structure, the necessity of parallel control to the fragments is presented. The shell shape of structures has an influence on the fragment spatial distribution. A new design method for the shel...

摘要:Abstract(#br)The quasi-static tests are conducted on three types of energy-absorption combined hexagonal aluminium honeycomb structures, i.e. traditional single-layer honeycomb, two-layer combined honeycombs at the stacking angles of 0° and 90°, and four-layer combined honey...
