A set of 5 large fragments from a 25 lb. forged steel has been examined metallurgically. Microphotographs showing strain patterns and incipient cracks indicate the manner in which fracture occurs. A simple paper model illustrates the general mode of fracture of a tubular shell or bomb, the first fractures being due to longitudinal shearing followed by a transverse tearing action which results in a fibrous fracture.
