Analysis on interruption of propagation of detonation during a pre - splitting blasting 一次預(yù)裂爆破傳爆中斷的原因分析
With the hepale code , the simulated results are reported about problems of plate impact , the copper bar impacted the rigid well ( taylor bar ) , the propagation of detonation , and the motion of a plane and a cylinder shell driven by explosives , and they are basically in agreement with experiment , as well as one obtained by ls - dyna 應(yīng)用hepale程序?qū)ζ矫媾鲎?、銅棒碰撞剛性壁( taylor桿問(wèn)題) 、爆轟波的傳播、炸藥驅(qū)動(dòng)金屬平板和柱殼進(jìn)行了數(shù)值模擬,并與有關(guān)理論解析結(jié)果或者實(shí)驗(yàn)結(jié)果以及l(fā)s - dyna程序、 lagrange程序的計(jì)算結(jié)果進(jìn)行了比較,符合程度較好。
Based on the shale code , the early code of ale , the two dimensional finite difference elastic - plastic flow code hepale has been developed , in which the ideal elastic - plastic model and equation of state of gruneisen are used to describe the solid material , the programmed burn technique is used to simulate the propagation of detonation , and the equation of state of jwl is used to describe the detonation products 借助于ale方法的早期程序shale的基本框架,開(kāi)發(fā)研制了二維彈塑性流ale方法計(jì)算程序hepale 。程序包含用彈塑性本構(gòu)模型和gr nrisen狀態(tài)方程來(lái)描述固體材料的行為;采用jwl狀態(tài)方程來(lái)描述爆轟產(chǎn)物的性質(zhì);采用程序燃燒法來(lái)模擬爆轟波陣面的傳播。
