爆炸焊驻点近区应变场分析

Analysis of Strain Field Near Stagnation Point in Explosive Welding

摘要:

采用理想流体对称碰撞模型沿流线研究了驻点近区的自然应变分布规律。计算结果表明，爆炸焊接驻点的应变为无穷大；在驻点附近5倍射流厚度范围内应变完成了突变。

Abstract:

In this paper,an ideal liquid model of s ym metrically colliding was taken to analyze the distribution character of natural strain field.The results show that the strain at stagnation point is infinite, and stra in saltaion is completed in fivefold jet thickness at explosive welding interface.
