Abstract

In this study, the impact of the explosion on the compound pressure vessel has been investigated. The main aim of this research is to discover new methods to enhance the performance of pressure vessels under explosive conditions and reduce associated risks. For this purpose, Abaqus software and Python numerical programming have been used to simulate a pressure vessel that is completely made of nickel and covered with C glass composite coating with a diameter of 984.25 in and a wall thickness of 0.73 in. The results indicate that the stress-strain distribution on the surface of the composite overwrapped pressure vessel (COPV) is uniform, and its potential values are found in the upper polar part of COPV. Also, by changing the fiber twist angle from 0° to 90°, the maximum pressure in the vessel wall can be reduced by 30% and the resistance to failure and damage can be increased by 50%. The results of the research indicate an increase in the resistance of pressure vessels with composite coatings in dealing with explosions and reducing the effects of waves.
