AN ANALYSIS OF THE FORCES AND BENDING MOMENTS GENERATED DURING THE NRL DYNAMIC TEAR TEST.

Abstract

An analysis is presented which predicts the hammer forces, specimen bending moments, and tear energies, generated during the NRL Dynamic Tear test. The theoretical predictions agree quite well with experimental observations for relatively brittle materials. The tear energy per unit net area calculated from this analysis is shown to vary significantly with initial impact velocity and specimen length for a brittle material. It is relatively independent of the specimen thickness and notch depth to width ratio. (Author)
