Design for Mechanical Fatigue: Predicting mechanical failure under

Equation of Goodman line:! Mean stress, σ m, as mid-range strength S m Alternating stress amplitude, τ a,! as fatigue strength S as Goodman Diagram for Torsion: Failure with τ … (approximately >10,000 cycles). In the low-cycle fatigue regime (approxi-mately <10,000 cycles), most of the fatigue life is spent on crack propagation. Once a crack has formed or complete failure has occurred, the surface of a fatigue failure can be inspected.

failure. Fatigue failure happens at a sudden without any hint (i.e. without any deformation). For other failure theories, the same principles can be applied. The standard stress versus cycles to failure data for unnotched laminates provides the determination of necessary parameters for the KTF. Using the test data to calculate endurance limit of the spring steels using Gerber, Sines and Goodman fatigue failure theories. Endurance limit indicates infinite life for a material.
