Flexural fatigue endurance limit

The flexural fatigue endurance limit (ASTM D671) provides Information on the ability of a material to resist mechanical... 

The flexural fatigue strengths and endurance limits have been reported for polypropylene FRC with various fibre contents. Specifically, the addition of polypropylene fibres, even in small amounts, has increased the flexural fatigue strength. Using the same basic mixture proportions, the flexural fatigue strength was determined for three fibre contents (0.1, 0.2, and 0.3 vol%) and it was shown that the endurance limit for two million cycles had increased by 15-18% (Ramakrishnan et al, 1989).
