Fatigue Analysis - Free Fatigue Calculator:Fatigue Types

The failure or rupture of a plastic article under repeated cyclic stresses, at a point below the normal static breaking strength. Fatigue failure occurs when a specimen has completely fractured into two parts, has softened or has otherwise significantly reduced in stiffness by thermal heating or cracking. It can also be arbitrarily defined as having occurred when the specimen can no longer support the applied load within the deflection limits of the apparatus.

The most effective method of improving fatigue performance is improvements in design:

  • Eliminate or reduce stress raisers by streamlining the part
  • Avoid sharp surface tears resulting from punching, stamping, shearing, or other processes
  • Prevent the development of surface discontinuities during processing.
  • Reduce or eliminate tensile residual stresses caused by manufacturing.
  • Improve the details of fabrication and fastening procedure

Looks like simple enough. Isn't it? Its not though. Fatigue is very critical criteria needs to be considered in while designing a product. There have been so many calculations behind this Fatigue. Fatigue doesn't occur just like that it varies from component to component of same material, based on different applications etc., If you would like learn this Fatigue Formulas and how to plot Graphs for component life cycle.  How to predict to Fatigue and How to avoid it so that your final design of the product doesn't change much.


All these comes in one single basket in net ie., fatiguecalulator.
