材料强度对电磁驱动固体套筒内爆过程的影响
Effect of material strength on electromagnetic driven solid liner implosion
摘要
Abstract
The electromagnetic driven solid liner implosion is one of the high energy density physics (HEDP)experimental techniques.Because of the metal strength,there exists a threshold for driven pressure where plastic flow j ust begins.And the plastic work that will turn to the internal energy of the metal liner should decrease the kinetic energy of liner,which of course will affect the implosion of the solid liner.The critical current has been found via the elastic-plastic analysis of cylindrical symmetry is-sue.The zero-dimension (0D)simulation considering the effect of material strength has been developed,whose result is also com-pared with the simple model and experimental data separately.The result shows that the effect of material strength is negligible when the peak value of current is far larger than the critical current,while the effect is remarkable when the peak value is similar to the critical current.关键词
