Abstract

An investigation has been carried out to examine the dynamic behaviour of crew module fairing subjected to blast loading. The objective of the present study is to determine the dynamic response of the crew module fairing with different type of construction such as metallic isogrid and metallic sandwich subjected to blast load. The crew module fairing is modelled as a shell structure with rings provided at different levels with different thickness. The sandwich structure consists of Aluminium honeycomb core with Aluminium face skin. The blast load acting on the structure is applied as a pressure- time curve and it is a triangular pulse with a rise time of 1 milliseconds and decay time of 6 milliseconds. The dynamic response of the metallic sandwich and isogrid crew module fairing structure are compared. The linear dynamic analysis is carried out using the software ABAQUS.
