Polypropylene Fatigue File Directory :
Updates: Dec.2009, Oct.2010, Jun2011
Note! : The pages and files in this directory are offered by the F.D.+ E. committee
members as a set of example files for the construction of web based material fatigue
property databases. They are meant for information and research use only, not for design.
Polypropylene, reinforced 2.3-3.0mm_GlassFibers, 120degC:
- Strain-Life test Data plot,
__ | __Cyclic Stress-Strain Curve
Fatigue test data points have been fitted by a High, Median, and Low
curve int the Strain-Life figure linked above. These curves are used to
create the three analysis variations below. Only one median cyclic stress-strain
curve(above) has been utilized in the "Fitted" and "Calculator" files below. (FAC)
