MetadataShow full item record
A survey of developments in the field of crack propagation and an experimental investigation of the strain distribution around fatigue cracks in flat aluminum sheets was conducted by Lt. E. B. Tucker, USN, at the Aeronautical Engineering Department of the U. S. Naval Postgraduate School, Monterey, California. Crack propagation was produced by constant stress reverse bending. Crack propagation rates were determined for both central and edge cracks. The nature of the geometry in the thickness direction around the crack tip was described and analyzed with the aid of Newton's Interference Fringes. A possible adaption of the method with the birefrlngent coating technique is suggested for further study.
