摘要
The shear fatigued performance of stainless steel diamond cores has been measured and S-N curves reported for two core relative densities. The fatigue mechanism for the low relative density core involves the successive bending fatigue of constituent struts near the ends of the specimen, while the high density core fails by fatigue failure of the joints between the core and the face-sheets. A significant knock-down in the fatigue shear strength of the core is observed compared to its monotonic strength. (c) 2007 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
