| Research Abstract |
Hypervelocity impact tests have been conducted for spacecraft or celestial body composed of specific and simple target, and furthermore wider and detailed study is required for predicting future space debris environment. We developed new SPH and orbital computation code that are able to be run on GPGPU. Especially increasing secondary small debris called ejecta is becoming serious problem currently, hence this research enables to further accelerate investigation of the phenomena that have had difficulty in computation. Besides it is applicable for complex structure by comparing to experimental results, and it was found that the phenomena highly depends on internal distribution of mass and impact direction.
