Numerical simulation of hypervelocity impacts of space debris using SPH method;

The microwave radiation intensity measurement on hypervelocity impacts were conducted with the 8 mm microwave radiometer at the hypervelocity impact facility at HAI,CARDC.

Considering the relations between the damage of space vehicle suffered in hypervelocity oblique impact and the configuration of the secondary debris cloud,Smoothed Particle Hydrodynamics(SPH) technique is applied to study the configuration of the debris cloud generated in a hypervelocity oblique impact.

Investigates the distribution characteristics of secondary debris clouds generated during a hypervelocity oblique impact.

The numerical simulation of the penetration and debris clouds is performed that columnar bar of high velocity impacts on thin steel plates with this method,and the problem is solved that how to found the SPH element model of the columnar bar,and the mechanism of forming process is analysed.

The numerical simulation of the penetration,particle splashing and debris clouds were performed that columnar bar with high velocity impacted on thin steel plates with this method,and the problem were solved to found the SPH element model of the columnar bar,and the mechanism of forming process was analysed.

Based on finite element discreteness method of continuous mechanics conservation equations, this paper establishes three dimensional finite element formulations and discretized equations in high velocity impact phenomena.
