IMPACT OF MISSILE ON CONCRETE OR SOIL OBSTACLE

Abstract eng:
Missile-Target interaction analysis is usually based on three essential assumptions and simplifications used to analyze this problem. In this paper the problem of interaction analysis is applied to impact of large body (an airplane, vehicle or a rocket) or small body (concrete fragments) of cylindrical shape as a rule, on concrete obstacle or on soil ground (soils, hard rocks, layered bedrock). In this sense, the paper focuses on impacts of flying body on building structure or on soil in its vicinity. A moving body or its parts may hit various types of structures, and missiles may also enter inside areas of objects through light structures. The impact theory was used to solve the residual mass and velocity of impacting missile, kind of target failure and missile penetration in obstacle. This methodology is based on kinetic energy transfer of the hitting object to the building structure. In this sense, contact areas of the building structure and of the moving object usually need to be specified, based on simplifications of the impact surface of its solid parts.
