A mechanism is advanced for the reduced fracture stress and ductility of metals tested in a liquid metal environment compared to the corresponding properties in air. It is proposed that if the stress necessary to extend 8 craok is calculated on the basis of the rupture of atomic bonds by tensile str
## Abstract The purpose of this investigation was to apply the techniques of fracture mechanics to a study of fatigue crack propagation in compact bone. Small cracks parallel to the long axis of the bone were initiated in standardized specimens of bovine bone. Crack growth was achieved by cyclicall
The crack propagation velocity in corroGon fatigue (du/dN), were measured on the Ni-Cr-Mo steel quenched and tempered at 473 or 773 K. The steel with high sensitivity to delayed failure reveals the largest (du/dN), under square load and the smaller (da/dN), under positive saw tooth load. The frequen
It is shown thet while moat commonly brittle fracture by liquid metal wetting will initiate at grain boundaries on the surface of 8 specimen, cracking can, in 8 number of instences, be induced in the centers of greins and out of cony contact with grain boundaries. Studies on 70/30 brass demonstrate
