slugEXPERIMENTAL ANALYSIS OF AN EXPLOSIVE TEST CHAMBER SUBJECTED TO INTERNAL BLAST LOADING
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2013, Vol 1, Issue 5
Abstract
Explosive test chambers are huge closed chambers used in research, testing of explosive materials and armor, research, and testing of nature of explosives used in military and defense weapons. The chamber is a huge, cylindrically closed, and is reusable. The material of the chamber is structural steel. After initial observations; an experiment is conducted on a volumetrically scaled model. The prototype, which is cylindrical GI container, is closed on both ends. A simple festival cracker is used as an explosive that is placed exactly at the centre of the container. The experimental setup is totally fixed. A camera with 15 frames per second is used to capture the experiment. The deformations are measured using dial vernier, dial gauge etc. The prototype is then modeled in ANSYS with same boundary conditions as for experiment and internal pressure is applied. The time step given is taken from the experiment. The pressure values are validated. Finally, the values are tabulated comparing experimental and FEA results for prototype.
