Designing for High-Cycle Biaxial Fatigue Using Surface Strain Records

Source

A method of designing for high-cycle biaxial fatigue using surface strain records is proposed. The irregular strain records are first idealized to cycles of constant amplitude to enable a first estimate of long-life capability to be made from allowable surface strain envelopes. These are developed from a criterion of failure under biaxial fatigue based on material bending and twisting fatigue properties. Methods of determining likely crack growth directions are also proposed. Important parameters to be considered in refining the initial approximate analysis are discussed.
