Paper Abstract

The key to conducting an accurate damage assessment of a structure that has been impacted by an orbital debris particle is the use of a robust assessment methodology. To accurately determine total structure damage, a damage assessment methodology must include the effects of descrete impacts by solid debris cloud fragments as well as impulsive loadings due to molten and vaporous debris cloud material. As a results, the amount of debris cloud material in each of the three states of matter must be known to accurately assess total damage due to a high speed orbital debris impact. This paper presents a first-principles based method to calculate 1) the amount of material in a debris cloud created by a perforating hypervelocity impact that is solid, molten, and vaporous, 2) the debris cloud leading edge, trailing edge, center-of-mass, and expansion velocities, and 3) the angular spread of the debris cloud material. The predictions of this methodology are compared with those of empirically based damage assessment schemes as well as against numerical and empirical results obtained in previous studies of debris cloud formation.
