• New Ideas in Fatigue Analysis
  components, unpredictable warranty claims, and loss of customer confidence. The challenge for software developers has been to deliver reliable fatigue-analysis tools because over designing components is no longer a viable option. In a nutshell, fatigue failures stem from small cracks that initiate...
• Characterizing Fatigue and Fracture Response (.pdf)
  strain-controlled. environment, superelastic Nitinol was superior to stainless steels [3]. In this study, there is also. mention of how fatigue-crack propagation analysis may be used complementary to the results. from fatigue testing. A cyclic frequency of 1 000 revolutions per minute (RPM) was used...
• Multiaxial fatigue models the real world
  involving multiaxial repeated loads, fluctuating loads, and rapidly applied loads. Cracks, the major sign of fatigue, usually begin on a component's surface unless there is a flaw in the material. Therefore, the fatigue solver uses only the surface elements and nodes from the results. This eliminates...
• Improving The Fatigue Response Of Aerospace Structural Joints (.pdf)
  method of surface enhancement which induces deep. compressive residual stress by the forced application of a smooth rolling ball across the. surface of the metal. LPB produces a smooth, mirror-like surface and minimal cold working,. and has been shown to improve fatigue, fretting fatigue and stress...
• Characterizing Fatigue Response of Nickel-Titanium (.pdf)
  the impact of melt origin on fatigue. performance 1 . This research compared the melting practices, final workings, and final shape-. setting heat treatment in the metal; however, fatigue lives did not differ for each supplier through. bending strains of 0.72, 0.84, 1.0, 1.2, 1.7, and 2.5 %. Figures 1...
• The Significance of Melt Practice on Fatigue Properties (.pdf)
  In continuation of a previous comparison of the influence of melt practice and strain amplitude on Ni 56wt%-Ti 0.267 mm wire, this investigation explores the fatigue properties at 0.127 mm of the same melt lots. By employing the same rotary beam fatigue testing, material with equivalent...
• Improved Fatigue Performance of Friction Stir Welds with Low Plasticity Burnishing: Residual Stress Design and Fatigue Performance Assessment (.pdf)
  AFGROW. A. 9.5mm (thick). The plates contained a single. semi-circular starting surface crack of 100 microns. weld in the center down the 914 mm length. (0.004 in.) was assumed for untreated specimens. HCF performance for salt fog pitted samples was. High Cycle Fatigue Testing. predicted assuming...

• An Investigation of Diverse Surface Finishes on Fatigue Properties of Superelastic Nitinol Wire (.pdf)
  . testing (RBT) of superelastic nitinol wires prepared with. seven different surface conditions. When studying fatigue. Our study has followed the RBT test protocol developed by. life three major considerations effect crack initiation and. Patel [5]. propagation leading to failure in nitinol wires...
