Static penetration assessment of stone weapon tip geometry metrics and comparison of static and dynamic penetration depths

Many factors governed the penetration efficacy of prehistoric projectile weaponry. Archaeologists broadly focus their efforts on understanding effect stone weapon tips because these specimens are often only part system that survives in archaeological record. The tip cross-sectional area (TCSA) and perimeter (TCSP) have been shown to correlate with target depth. Here, using results from both static dynamic testing, we compare TCSA TCSP against other geometry metrics: lateral surface (LSA) volume (V). Our analyses show a single-point metric evaluated at multiple locations along length point, or metrics single location, better predicts required energy than location. also case where is used LSA provided most robust prediction models. Finally, our for all location provides model dependent how far point penetrated target.
