V-NOTCHED COMPONENTS UNDER TORSIONAL FATIGUE LOADING [Keynote]
Alberto SaporaDogwood B
Finite Fracture Mechanics (FFM) is applied to assess the brittle or quasi-brittle failure initiation at sharp V-notches under torsional loading. By assuming that failure is shear stress governed, the approach is developed in the fatigue framework. The analysis includes a discussion on the calibration of the material properties, and the comparison with experimental data available in the literature.
