Abstract: | It is important to analyze the distribution of the strain rate near the welding interface in order to understand the mechanical and heat behaviors of a material during explosive welding. The objectives of this study were to analyze the distribution of the strain rate for different colliding angles and to probe the effects of the colliding angle on the strain rate. An ideal fluid model of symmetrical collision was used. For the same relative streamline, at the points with the same relative horizontal ordinate, calculations showed that the ratio of tensile and shear strain rate to the stagnation point strain rate is very similar for colliding angles in the range 6–20°. |
