The method of smooth particle hydrodynamics and the ANSYS AUTODYN software are used to reproduce the main phenomena accompanying high-velocity collision of plates fabricated from iron and copper of commercial purity. The maximum true strain of the surface layers is determined to attain ε = 5 or higher values. It is shown experimentally that defects with a length comparable to the thickness of the original plates do not form under welding by optimum modes. Growth in the strength properties is a factor promoting formation of bands of localized flow under rapid loading. Defects of this kind correspond to the behavior of positive feedback loops. The width of the bands arising under explosion welding of plates from a two-phase (α + β) titanium alloy VT23 ranges from units to tens of micrometers.

光滑粒子流体动力学方法和 ANSYS AUTODYN 软件用于再现由商业纯度的铁和铜制成的板的高速碰撞伴随的主要现象。确定表面层的最大真实应变以达到 ε = 5 或更高的值。实验表明，长度与原板厚度相当的缺陷在采用最佳模式焊接时不会形成。强度性能的增长是促进在快速加载下形成局部流动带的一个因素。这种缺陷对应于正反馈回路的行为。两相（α+β）钛合金VT23板在爆炸焊接下产生的带的宽度从单位到几十微米不等。
