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.

A new adaptive SPH method for hypervelocity impact simulation

Numerical examples for hypervelocity impact by the coupled method show that the coupled method is a more efficient method to simulation of large deformation problem.

Several problems which should be taken into account in numerical study of hypervelocity impact are stressed and the effective measures to solve them are also described in the paper.

Visible spectral radiant intensity measuring technology for hypervelocity impact phenomena;

Simulation of hypervelocity impact to honeycomb sandwich;

Applications of the smoothed particle hydrodynamics method to hypervelocity impact simulations;

Numerical analysis of space debris hypervelocity impacts;

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.
