A parametric study of high velocity impact prediction using the Mie‐Grüneisen equation

Space debris is a serious threat to space travel. Even small fragments are enough damage or destroy satellites. To protect against debris, satellites have protective shields, which come in various forms. These shields must be optimized not only for impact protection but also secondary factors such as weight and size. New shield systems can tested experimentally with high-speed guns. This requires lot of time, energy, cost. Here, numerical solvers used evaluate these new systems. For example, the smoothed-particle-hydrodynamics (SPH) method commonly simulate large deformations resulting from an impact. Special equations state capture effects that occur. One model Mie-Grüneisen equation state. It widely this application does account physical occur at very high speeds. Other, more complex cover effects, they often implemented commercial ABAQUS. Here we show lead quantitatively reasonable results compared experimental tests hypervelocity impacts ranges up 10 km/s, even though covered. A parametric study shows predict plate collapse function impactor diameter velocity target thicknesses. Initial designs isotropic thus numerically low effort
