Fatigue and Risk Index Calculator v2.3 Before using for the first time, users are recommended to read the user manual and the research report describing the tool development (especially section 2). This is possibly related to the probability of a high stress interacting with a critical flaw within a certain volume, i.e., when the volume is large there is a higher probability of failure. 1) Input Applied Stress 2) Input Material Data 3) Include Cast Factor (reduced fatigue performance due to casting defects). The key considerations should be the principles contained in HSE's guidance. National Work Stress Network, UK. Purpose of calculation: Produce Wohler /S-N Plots and Goodman Diagram Plot.

No warranty or representation is made as to its accuracy or completeness. More than 3.5 million people are employed as shift workers in the UK. Once you click calculate, you will be taken to your results, where you will be able to generate a PDF report and see a detailed breakdown of the calculation. Downloads: 11. Axial loads, shear loads, thermal loads, and thread tear out are used in factor of safety calculations. Alternatively, since there appears to be a more pronounced size effect in reversed bending and/or torsion than in the reversed axial loading situation this suggests that the stress gradient at the surface is partially responsible for the size effect.Surface finish factor. Fatigue has also been implicated in 20% of accidents on major roads and is said to cost the UK 115 - 240 million per year in terms of work accidents alone.
