...Jianfeng Xu; Izhak Etsion; Frank E. Talke The failure due to accidental drop of magnetic recording disks made of brittle or ductile materials is of great interest in the design of small form factor hard disk drives. In this study, fracture of glass disks (brittle material) and plastic deformation...

... of ductile metals loaded in fatigue with positive mean and alternating stresses. However, all of these diagrams are either conservative, or have domains containing stress greater than yield strength of material. This paper presents the Clemson diagram, which has the same format as the aforementioned diagrams...
