During the early stages of an impact a small amount material may be jetted and ejected at speeds exceeding the impact velocity. Jetting is an important process for producing melt during relatively low velocity impacts. How impact angle affects the jetting process has yet to be fully understood. Here, we simulate jetting during oblique impacts using the iSALE …

In forensic science, the angle of impact is the angle at which a blood droplet impacts a surface. By definition, it is an acute (or right) angle (varying from 0° to 90°). Knowing the angle of impact, detectives can partially reconstruct a crime scene by drawing "strings" from the spatter to an origin area.

The nip angle is affected by the distance between the rolls. The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle. It depends on the surface characteristics of the rolls. Usually, the nip angle is between 20° and 30° but in some large roll crushers it is up to 40°.

on impact angle; for impact angles less than 45, most of the jet is composed of impactor material, while at higher impact angles the jet is dominated by target material. Our ndings are consistent with previous experimental work. In all cases, jetted materials are preferentially distributed downrange of the impactor.
