摘要：A blast is the immediate vicinity of a vehicle can cause catastrophic damage on the vehicle's external and internal structural frames. This kind of scenario is expected to armed vehicles of defence department. It is hoped that the blast take plac e from a distance to the vehicle. This distance is called as standoff distance. In addition, major catastrophes resulting from explosions result in large dynamic loads, greater than the original design loads. Due to the threat from such extreme loading con ditions, efforts have been made during the past three decades to develop methods of structural analysis and design to resist blast loads. The analysis and design of structures of vehicle subjected to blast loads require a detailed understanding of blast ph enomena and the dynamic response of various structural elements. Elaborate experiments were at university of Sheffield and also by defence sector, to find the transients of the pressure developed by explosion/blast. In this project an attempt is made to de termine the stress field developed in the plates of the vehicle for an impulse/blast. This project is aimed at an analysis of an ordnance vehicle undergoing explosive loads due to detonation. This project starts with a comprehensive overview of the effects of explosion on MPV (Mine Protected Vehicle). An explanation of the nature of explosions, their interaction with a structure, stress distribution and displacement of the special vehicle (MPV). In order to evaluate the stress and displacement finite element analyses are performed using ANSYS software for different Blast loads and boundary conditions.
