Data concerning the rigid/eroding-rod threshold transition are reported for hemispherical-nosed tungsten rods penetrating into thick 5083-aluminum targets. Presented data quantitatively buttress existing explanations. The current analysis suggests that the penetrator must bring to bear a different "apparent" strength in the noneroding- vs. the eroding-penetration regimes. Conventional one-dimensional penetration analysis reveals that the noneroding datum is wholly consistent with the notion of treating the rod as if it penetrated in a rigid-body fashion, possessing unrealistically high yield strength. Study of a recovered rod fragment reveals that the penetrating rod nonetheless deformed, but did so without erosion. Such an observation for hemispherical-nosed rods is consistent with past qualitative explanations posited for ogival-nosed rods. The phenomenon, supported by analysis, is that an exaggerated stress was axially applied by the rod to the target interface, composed of both the rod's intrinsic yield strength plus a confining stress caused by a lateral interference fit between the rod and target during the penetration event.
