不同加筋结构在水中接触爆炸下的破损规律
Damage of different reinforced structures subjected to underwater contact explosion
摘要
Abstract
LS-DYNA was used to simulate the responses of different reinforced structures subjected to underwater contact explosion by considering different reinforcement strengths and locations. Strength and distance factors were defined to describe the strength and locations of stiffeners, respectively. Six models were proposed with different strengths of stiffeners and three models were developed with different locations of stiffeners. Typical damage processes of the reinforced structures were analyzed. The horizontal and vertical crack lengths of crevasse were compared as well as crevasse area. The effects of the strength and distance factors were found on the reinforced structures subjected to underwater contact explosion. The results show that it can be effective to restrain crevasse area when the strength factor rises in the vertical direction and it is not significant when the strength factor rises in the horizontal direction. The distance factor is in direct proportion to crevasse area and the crevasse shapes are related to both of the two factors defined.关键词
