Abstract:

The United States is slowly moving towards lunar base, and possibly Mars base, activities. Design of structures for these bases requires knowledge about loadings and conditions which in some cases are essentially nonexistent on Earth. This paper examines one of these loadings, meteoroid impact. Reliability analyses were performed for two limit states related to meteoroid impact. The first is complete penetration of a structure by a single impacting meteoroid. The second is accumulated damage by a sequence of strikes on the same area of the structure.
