Abstract

Dynamic impacts caused by explosions from weapon systems are crucial in the design of Air Force structures such as Hardened Aircraft Shelters or steel aircraft maintenance hangars. The influence of such loads on the response of structures depends on the distance of the explosion from the structure as well as on the weapon. This research investigates the influence of the distance of the explosion on a dynamic impact due to a GP750 (M117) bomb explosion on the response behavior of a 3rd generation Hardened Aircraft Shelter (H.A.S). Parametric finite element analysis is conducted to demonstrate the effects of a GP750 -M117 bomb on a NATO 3rd generation Hardened Aircraft Shelter (H.A.S). The parameter which varies is the distance of the structure from the blast point.
