The significance of different Pi terms which result from a dimensional analysis of the parameters involved in hypervelocity impact is discussed. The consequences of distorting some physical phenomena in models are analyzed, and experimental verification Is presented for the use of replica and dissim

SPH (Smooth Particle Hydrodynamics) is a relatively new gridless Lagrangian numerical technique which offers advantages over more established grid based Lagrange and Euler methods. An SPH capability implemented into the AUTODYN-2D software has been used to simulate hypervelocity impacts on thin Whip
This study focuses on the simulation of hypervelocity impact problems with different equations of state (EOSs). We used a high-order multi-material Godunov method in Eulerian form and applied an ''exact'' multi-material Riemann solver to find more accurate individual phase advection fluxes regardles
Bacteria belonging to the genus Rhodococcus have been tested for their survivability in hypervelocity impacts at 5.1 Β± 0.1 km s -1 . This is similar to the martian escape velocity for example but is slower than the mean velocities typical of impacts from space on planets like Mars (typically 14 km s
