    Cylindrical imploding shocks are analyzed numerically. The shocks are supposed to be generated by detonating cylindrical explosive shells. Detonations are assumed to be initiated either from the inner or the outer surface of the shells. Explosive shells of different thicknesses are compared. The...

    Experiments have been done to obtain product isentropes of the plastic bonded TATB explosive PBX 9502. A thin aluminum flyer was thrown at an explosive disk so as to generate a state in excess of the Chapman-Jouguet pressure. Because the flyer is thin, the shock wave is followed by a release...

    The aim of this study is to develop a reactive burn model based upon a microscopic hot spot model to compute the shock-initiation of pressed TATB high explosives. Such a model has been implemented in a lagrangian hydrodynamic code. In our calculations, 8 pore radii, ranging from 40 nm to 0.63...

  • shock wave.  // American Heritage Student Science Dictionary;2009, p308 

    A definition of the term "shock wave" is presented. It refers to a large-amplitude wave formed by the sudden compression of the medium through which the wave moves. Shock waves can be caused by explosions or by objects moving through a fluid at a speed greater than the speed of sound.
