Abstract:

The purpose of this report is to apply the nick-break weld joint fracture and bend fracture tests, as developed in connection with a recent examination of thirty-three commercially welded H plates ballistically tested at normal temperatures , as a means of clarifying the principal conditions attributed to inferior ballistic performance of the subject plates. It was desired to hold metallographic work to a minimum, but investigating by means of notched bar impact tests and microscopic examination any deleterious metallurgical condictions not previously observed.
