爆轰波碰撞聚能无网格 MPM 法数值模拟
Simulation on assembling energy of detonation wave by using MPM
摘要
Abstract
Assembling energy of detonation waves is usually applied in blast cutting project .To explore a kind of new method for assembling energy ,one column shape charge with multi-lighter points is de-signed .Collision of detonation waves and pressure field of explosion products are simulated by using the material point method with explicit algorithm .By comparison with experiments ,numerical simulation of the material point method can attain better calculation precision .Furthermore ,one new technique can be also provided for assembling energy of detonation waves.关键词
