High energy density physics deals with behavior of matter under extreme conditions of pressure and temperature. Several fields of research involve high energy density: astrophysics, geophysics, inertial confinement fusion (ICF), explosive and impact loading of materials, Z-pinch devices, etc. All of these fields involve one common feature: i.e., concentration of an intense source of energy in a...

In this paper, the energy absorption features of tri-layer explosive-welded deep-drawn cups subjected to quasi-static axial compressive loading are investigated numerically and experimentally. To produce the cups, tri-layer blanks composed of aluminum and stainless steel alloys were fabricated by an explosive-welding process and formed by a deep drawing setup. The quasi-static tests were carrie...

The development of material laws for concrete subjected to explosive loading which cause high pressure and extreme strain rates is a subject of current research. In some international codes for designing structural concrete the dependence of certain material properties, as strength in compression as well as tension and stiffness, on strain rates up to 10̂ [j] has already been introduced and is u...

The Rayleigh–Taylor instability in metal is of great practical interest to a diverse range fields, and it significantly different from the traditional fluid interface instability. In this paper, set high explosives driven experiments copper plate are presented for intensively understanding perturbation growth behavior history on at specific time recorded by flash radiography. experimental resul...

Metal/fluoropolymer composites represent a new category of energetic structural materials that release energy through exothermic chemical reactions initiated under shock loading conditions. This paper describes an experiment designed to study the reaction characteristics of energetic materials with low porosity under explosive loading. Three PTFE (polytetrafluoroethylene)/Ti/W mixtures with dif...
