FORCES RESULTING FROM BAT IMPACT ON THE CHEST OF

Abstract

Th effect of inertia was Investigated by impacting a Hybrid II mannequin in constrained and unconstrained configurations with a baseball bat swung at an angular velocity representative of a typical blow. The forces induced by the blow from a bat to the chest of the mannequin were found to be equivalent for both configurations. An analytical model of blunt Impact used to validate the findings and provide insight into the physical phenomenon, suggests that the effect of inertia only becomes prevalent when the mass of the impactor is substantial as compared to that of the mannequin.
