A REVIEW OF RECENT INVESTIGATIONS INTO FRACTURE INITIATION AT GALCIT.

Abstract

Investigations into the mechanics of fracture initiation have been made with especial emphasis on the effects of initial sheet curvature, the interaction of applied extensional and bending stresses, the role of plastic flow near the crack tip, and the significance of finite plate thickness. There has also been some work performed along more classical lines including a review of Griffith's theory of brittle fracture, an analysis of a penny-shaped crack in a shear field, and a study of certain analytical methods for treating crack problems.
